this is my first post to the list.

I think I've got this problem since last tuesday when I've put in
production state my first SLES9.

I have lots of connections in TIME_WAIT state. As I understand the
TIME_WAIT state is used to indicate that a closing socket still have to
manage some packets in the network before "disapear".

My /proc/sys/net/ipv4/tcp_fin_timeout is set to 30 seconds, and
apparently most (all?) connections are ending by this timeout, not by

Most of the sockets interconnect processes running in the very same
machine, I don't understand why is the timeout reached. I supose this
would be a normal situation with a slow machine, but this is a new one
with 2 Xeon processors @ 3GHz and 2 GB of ram, it only have to handle 1
Mbps of internet connection. I cannot put into production the old
machine to compare them.

As as second problem the machine stales for various seconds (5 to 20)
from time to time. I've also changed the NIC, but the situation is still

I've applied all possible patches, the OS is up to date.

Running processes:
apache2 (prefork)
imss, interscan antivirus daemon, postfix content filter

netstat -nep
see the attached file.

Best regards,
Ernesto Silva.
