Server crashes like every 2 minutes

Hi everyone!
I have been playing on a server and I keep get an error.

Code:

java.net.SocketTimeoutException: Read timed out
at java.net.SocketINputStream.socketRead0
at java.net.SocketInputStream.read (Unknown source)
at java.net.SocketInputStream.read (Unknown source)
at java.net.SocketInputStream.read (Unknown source)
at java.io.FilterInputStream.read (Unknown source)
at abs.a(SourceFile:145)
at lg.e(NetworkManager.java:227)
at lg.c(NetworkManager.java:389)
at rl.run(SourceFile:76)

How can I fix this. (I have acces to the server)

Thanks!

EDIT: I think
2GHz Dual-Core
2GB RAM
Windows XP x86
about 30 plug(ins) (don't know exact)
CraftBukkit #2222

EDIT2: I think it was the My Worlds plugin.. now less worlds and only 1 crash in 3 hours..
