I'm running a server for my friends and I. It just crashed and I'd like to know why (It's not an urgent problem because I can just restart it and it's fine). I don't really know how to read crash reports so if someone who does know how can give me like a tl;dr on what this means, I'd really appreciate it.
The computer is really bad so I expect it's just that it couldn't keep up, but I thought I'd come here in case the crash was caused by something that I can fix. Thank you in advance!

How bad is "bad"? Server crashed because it didn't respond for over a minute. Try allocating more RAM.
