0, 0 problem ?

Hello,

i've seen a problem in my console these days, it does :

14:32:51 [INFO] 0, 0
14:33:21 [INFO] 0, 0
14:33:23 [INFO] 0, 0
14:33:34 [INFO] 0, 0
14:34:37 [INFO] 0, 0

everytime, how can i correct that 0, 0 messages ?

And after some 0, 0, i have :

14:47:15 [GRAVE] java.lang.IllegalStateException: TickNextTick list out of synch

and server crashes :/

Thanks

 

i hae seen the [Info] 0,0 before but i have no idea what it means

 

And the error causes the server to crash ?

 

no it causes people to disconnect. i have the same problem as well.

 

test which plugin is causing it.

 

and the fatal error ? anyone knows what it is ?
