We have been playing on MindCrack v1.3.2 (MC v1.5.7) server for more then a month without any major problems, until recently.
Now we have the following problem, on which I have spent 2 full days of googling and repairing, but with no luck.
After I start the server, it will run for random amount of time (usually 3-5 minutes, longest ever is 30).
After that it will crash, but in a way you don't get a crash report.
The thing is, at the time the server crashes, anyone who was on the server will still be able to
walk through already loaded chunks (but not generate a new ones) and talk in chat.
They won't, however, be able to open the doors and make changes in the world.
No new players will be able to connect, and all players currently on the server will be kicked in the short time afterwards.
So, when trying to connect from the launcher, server will look like it's offline, but when I connect to server through SSH,
and recall the screen, it is still online, at least it looks like it is.
Because it is still online, there is no crash report generated, as it didn't crash.
I left it for like 2 days in that state, at it kept on running. Out of 50 times I tried restarting it,
crash log has been generated only 2 times, so I can't really know if it's related to the main problem,
but just for the sake of it, here it is: http://pastebin.com/raw.php?i=zRSfxMAX
I have ran out of ideas, so I decided to ask for help here.
Any kind of help is appreciated.
