Subject: [suse-sles-e] SLES 9 server hangs

Hello,

I use a SLES 9 server as a mailrelay with postfix. After a logrotate the
firewall stops logging to syslog and begins to log to the console.
Two hours later the server hangs and I have to do a hard reboot. But the
server was available from outside. It answered to a ping.
It seams that the load was to high.

Has anybody an idea what can be the fault?

Thanks for help
Stefan

Here is the firewall-logfile:
