Hello, Recently, well, for quite a while now I've been having completely random crashes, such "timeouts" that just occur at random points. It doesn't give me a specific error, it just looks like this: http://pastie.org/5059141 (format is a little weird) - What basically happens, is that it just starts doing these "Read timed out" things. It would make sense if the server was "overloaded", but I doubt it is. When I check available memory it doesn't seem to be stressed, and it can happen completely random at 4 am in the night when 5 people are online and run fine next day with 40 online. It doesn't happen after a "specific" time either, it just happens like every 5 hours and it's starting to get really annoying. I heard of a program called "VisualVM", and I tried it, but I don't really understand how to use it that well. I have found a guide, with link: http://forums.bukkit.org/threads/wip-analysis-of-your-server-jvm-using-visualvm.66536/ But it doesn't really tell me what to look for when trying to find the reason for the crashes, like if there is a plugin overloading the server. I tried navigating around the program. I made a heapdump and checked under the "Instances [%]" where the guide lets go, but nothing seems to be taking power too much. Then I went to the Sampler tab, and I saw really high numbers on the CPU/Memory tab, but without knowing if these numbers actually mean anything I might aswell go draw an elephant in paint, so here you go: http://imgur.com/8kOBm As it turns out, I'm not very good at that either. Can anyone please help me to use this fine tool, VisualVM, to find out where I might look to find what is causing my server these issues?
