Server has random timeouts - no errors in console

    My server seems to have random timeouts. The timeouts don't follow any pattern, as far as we are aware, and they are random. What happens exactly is that server commands stop working and for about 5 seconds or so, players are still able to chat before they are hit with a "Connection Lost: Timed out." message. After that, players must wait a bit, like 15 seconds, 30 seconds, or a minute, before they are able to join the server again. The server shows no error messages (not even messages saying that players were disconnected from the server) through the entire process, but after the players can join again (in other words, after the timeout) that's when it says each player has disconnected and joined again.

    I believe it could be a memory issue and the server not being able to keep up. The reason I believe this is that sometimes we THINK there is a timeout because the comands stop working, but then it comes back after 3 seconds without timing out. When that happens, the console does say something like "WARN Can't keep up! Did the system time change, or is the server overloaded? Running 7251ms behind, skipping 145 tick(s)."

    I just switched to the 6gb "Dragon" service from MCProHosting.com and the problems still occurs so it cannot be the host. I believe one of the plugins is causing this problem, so if I could find a way to test it that'd be great.

    Another thing I've noticed (though it might be completely unrelated) is the console says "Unknown command. Type "help" for help." on a timely basis. I have tried removing all of my plugins (besides the core like Essentials and PEX) and this kept happening. I'm not sure what this means, but if anyone knows then that'd be great too! :)

    Kabino Do you have any un reliable or custom coded plugins in your server?

    Kabino I have no clue what is wrong with you server, maybe your should contact your host's support.

    The thing is, this happened on our previous host as well. The message we get is "Connection Lost: Timed out." and then the server just hangs for a bit. I thought maybe it was a memory issue, hence why I upgrade to 6gb. Is there anyway to run a "scan" of all plugins and see if any are using more memory than expected?

    We do have the same problem as well on our server, no errorlog, and CPU hangs for a bit.. enough for everyone to timeout. Then CPU revives and ppl log on again. No pattern whatsoever.
