[Samba] closewait socket state

Tue Jul 11 14:48:08 GMT 2006

I have a probleme with my samba server. I have a lot of closewait socket
state causing the load average to increase.
Samba generate some errors logs but I don't know the signification of
"Signal 7 in pid xxx".

For information, I am running a samba 3.0.10-1.4E.2 under a kernel Linux
version 2.6.9-22 with a RHEL 3.4.4-2.

Here is the log file (/var/log/messages) :
