Server crash after World Save

Hello. I've a problem with my server. My server crashes after some world saves. I've tried to change the save-time to 5 minutes, but after about 23 saves server keeps crashing. What have I to do? There isn't any error and my plugins work correctly; the server doesn't lag.

This is not a problem of the RAM, I have 16Gb and it crash with 20 Player too.

Build: Bukkit-1.7.2-R0.3

 

Can you provide a server log? Perhaps we can see something you missed.

 

After the save:


[16:40:49] [Server thread/INFO]: CONSOLE: Save complete.
[16:40:49] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 47083ms behind, skipping 941 tick(s)

[16:40:51] [Server thread/INFO]: ***NAME** lost connection: Disconnected

etc..

 

Can you provide the full log please?

 

There's a lot of confidential data in log files and I can't provide it (like IP of the users). Can you please tell me what do you want specifically?

 

I need all your players Ips to determine your problem.

 

Why would you need player IPs? I think that they can't let someone find the solution.

 

Speedys I was joking....

 

I have to correct the title. Server DOESN'T CRASH, but it throws out all users.

 

He wants the startup section, that shows your server booting up. There aren't any player IPs in that part, it just shows all of your plugins loading and sometimes gives clues as to what could be causing a crash.

 

There you go.
