Subject: linux 2.6.9 still having network code problems
Date: Tue, 02 Nov 2004 16:14:35 +0800 [thread overview]
Message-ID: <418741EB.3080701@outblaze.com> (raw)
Mr. Morton,
I'm ccing you due to the oom-killer stuff.
Previously with 2.6.7 I had to use this values in sysctl to be able to
continue to access the box:
net.ipv4.tcp_max_syn_backlog = 2048
net.ipv4.route.gc_thresh = 65536
net.ipv4.route.max_size = 1048576
2.6.9 without this values gave me similar problems with 2.6.7 without
the above values.
Sample log lines below:
There are multiple oom-killer lines (different pid for smtpd process)
and the network related messages repeated until the box was rebooted
about 45 mins later.
