I'm trying to build an item sorter in my 100% 1.6.2 vanilla smp, but for some reason the hoppers are acting all wonky. I've successfully built the standard hopper sorter (comparator, 2rsd, repeater into block /w not-gate torch...you know) a few times now, but the hoppers that hold the items to be sorted are not behaving. I set it up, and it looks ok, then when items actually start flowing in, they do not hold to 22 items, some of the hoppers will randomly start emptying altogether. Not all, just this one here, that one there, and I can't get them to all behave properly through a whole test run.
I've had my fair share of bugs with this "simple" contraption, but now I'm quite flummoxed.
Anyone else having issues with the hoppers? Any tips for troubleshooting?
Thanks!

Are you using this setup for your sorter (inlet line not shown):

Is your sorter constantly running while you do other stuff around your base? It could be that you are having "stuck" repeaters caused by the unloading of the chunks they are in.

Burgled beat me to it, but if you are using a water stream, try exchanging out to a hopper chain
A good point. It's also possible that too many items are being put through at once. If for example your input is a water stream then too many could be added at once, this will cause the power from the comparator to increase past 2 making adjacent sorters dump what they have. If that's the case then the easy solution is to use hoppers above as input since they will only send one item at a time.
No water stream--but in the initial testing, there was item backup. I went back after a bit to try again, cleared all the stuff from the system, reset it, and put a single item of the correct kind in the bottom (locked) hopper for good measure (I'd seen a kid on youtube do it, so I figured why not, while I'm at it). It's in spawn chunk, so it shouldn't be a matter of loading and unloading, I don't think, but hey.
I think it may've been the initial item backup. Or just sticky redstone--sometimes, I've noticed, repeaters act funny on this server during construction, and simply breaking and replacing fixes things. Which I also did.
I'll pop back on that server later today, and I hope to see it working.

I am having the same issue you are. Just plain buggy. And I've been using these sorters since the day the hopper was released! I know what I'm doing. By any chance are you on a bukkit server? That may be the culprit for the both of us.
I have items that dont enter the hopper (18-1-1-1-1 sitting there unphased) and go right past like the hopper didn't exist. Specifically Diamonds and Emeralds, Netherbrick, and someothers. Other times it will take one or two. Its not chunk loading, cause I'm standing and supervising. Does it with water and Hoppers, but with water I can watch it skip on by...
Used to be 99.9 % accurate sorting...now my trash chests at the end get most of the flow. And eventually every single chest in the sorter has odd items that just come on in.
The design they show above has a flaw, in that if tiled it has no overflow protection because the circuits are merged together. To correct that you'll want each circuit to be separated from one another.
This won't change the ability to be tiled, though it does change the design a little.
(use 1 of the item to be sorted, 17 cobblestone, 1, 1 and 1 cobble in the upper hopper and 1 of the item to sort in the lower hopper. This is referring to the two hoppers directly behind and above the chest)
Anything that has not been assigned a sort slot is fed to the waste chest on the opposite end from the collection chest, why people change it and do it other ways and then 'cry about it' when it doesn't work is totally beyond me, it seems they love to torture themselves; if not just to spite the simple.
Make this design every other row..
Then make this design every other 'opposing' row..
When side by side the two designs look like this, thus making each a 'separate circuit' and providing "overflow protection" because they come to a "complete stop" when "full", rather than flow into opposing hoppers and cause jams or mixed and messed up item placements.
The two designs paired, can be tiled infinitely as shown below...
Here's the world save from which I made these images, the .zip is direct with no ads and contains the save folder and .schematics for the pair, plus the larger grouped set shown above. http://puu.sh/43nTX.zip
Hope it helps!
Note: The lamps aren't required, though having them in place will indicate which chest is being filled when, as the lamp below each chest will turn off when the chest above it is being filled.
This method for "overflow protection" works insanely well, here's a sneak peak at what will soon be one of the largest "automatic mob farms" you have ever seen lol ..
Aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
I was having this problem too. What I found was, slowing down the flow of items into the first hopper made the problem go away. I did this by setting the repeater in my dropper elevator to 4 ticks. What I believe was happening is the redstone signal in each individual item sorter would leak into the next one if the items would go in too fast. The sorter is setup to turn the hopper on when it reaches 23 items. If the items come in too fast, its as if it has 24 items in it, which causes the redstone to extend just enough to turn the hopper next to it on.
A surefire solution is to leave one space between each sorter setup, but who wants to do that? My solution was to slow down the trickle of items as much as possible, and also to leave several of the target items in the sorting hopper. (I would have say 8 coal, then 11-1-1-1 of my filler item.) that way, if an odd redstone leak does happen, it would suck one or two of the coal blocks down, which would replace itself the next time I put coal in. I hope that made sense.
Anyway, I haven't had one problem since I slowed down the item input. The design above seems me like it works perfectly, but takes a lot resources.
My idea will only work if the items go through a dropper elevator before the sorters though, as thats the only way to slow down the item flow. I suppose you could actually make a clock on the input to slow it down as well, though.
I should add that Im not using a water flow. Im using hoppers for that. I think that water flow messes up the system by not flowing the items evenly. PS. I am on a bukkit server.

What part of "overflow protection" did you not understand? I use 1 double chest for collection and 1 for waste, you can clearly see them on each end of that massive beast above and it never ever jams or slows.

I had been through the same thing as you and spent weeks researching. Someone mentioned an overflow problem and I for get who made the Vidio but there is a salusion in a Visio called 1.6.1 item sorter overflow protector. Honestly I found it to be to complex, expensive and big. When the chest becomes full the hopper does to which in turn powers it on to give off a pulse. The torch that you place under it actually powers it off but when it's full the hopper turns off that torch and in turn breaks the circuit and then the hopper system before it breaks as well and stops sorting. If you put a lot of items in to sort then this can jam your system up quite a few chests. Separating your chests kind of helps, or you can use the expensive overflow protector, or did what I did and take cobblestone/dirt/redstone/even sand out of the system. The reason for the sorter for me was mainly to be able to find the abundance of random items I had easier anyways so the last was the easiestAlso I did need to rebuild all my broken circuits from scratch to reset them.
The only thing that causes over-flow is an interruption to the signal or merging of the signal. Hence why the design I posted pictures of, is showing how to "make the circuits separated" from one another. If they are separated then they are not merged.. just as an open door is not closed or a closed door is not open.. sometimes I feel as though I am talking to a wall lol ..

This may not apply in this case, but I put in a sorter in a zombie pigmen farm in the nether and it was missing items - it sorted most gold and rotten flesh just fine most of the time, but some would slip past the filters and end up in the dump chest at the end of the hopper "stream". I tried all sorts of things and couldn't eliminate the leakage. Then it suddenly dawned on me. The Zombies were dropping onto a 3x3 platform of hoppers and died and dropped their loot. I had them all fed into a single hopper which took the loot down one block level, then I had a chain (stream) of hoppers run right under the killing platform. The filter hoppers were on the next layer down from that (as you would expect). The problem was that when an item in a filter was in the stream hopper above it and also had just be collected by a killing hopper right above that, I ended up with two filters on top of each other and the newly collected item(s) would drop down into the stream hopper. That hopper couldn't handle two (or more) items at once, so it passed the excess items on down the stream and they didn't get sorted.
So, the moral of the story is, make sure you have a non-hopper in the block above the stream of hoppers in your sorter. In fact, if you don't want hopper "cross talk" you should avoid running a horizontal chain of hoppers right over another hopper(s). It's obvious to me now, but I was beating my head against the wall for two days trying to figure out what was going on!
I've had my fair share of bugs with this "simple" contraption, but now I'm quite flummoxed.
Anyone else having issues with the hoppers? Any tips for troubleshooting?
