current world is about 4 months old. this problem started month ago.. the problem is, that server generate errors every minute or so, and the longer server runs without restart, the more lags. they are not continuous, but occur every some seconds. So the server is set to restart every 8 hours

i just saw an interesting thing.

[Server thread/INFO]: Turned off world auto-saving

after this, no error was generated for 5 minutes, after that,

[Server thread/INFO]: Turned on world auto-saving

immediately errors started generating
i tryed it myself manually, and it seems like lags were gone too.

so..
disabling chickenchunks mod seems to solve this problem,
reenabling it bring back problem.. i hoped that removing all chunkloaders would be a solution..
