Subject: kernel BUG at net/ipv4/tcp_output.c:1006!
Date: Fri, 13 May 2011 13:11:52 -0400 [thread overview]
Message-ID: <4DCD6658.3020901@techboom.com> (raw)
This is the 2.6.38.5 kernel with the patch in
[PATCH] tcp_cubic: limit delayed_ack ratio to prevent divide error
Had this crash a few days ago, but never got any response to subsequent
emails. Another server crashed today with a network related backtrace,
but netconsole did not work.
The network switch is a
HP ProCurve J9147A 2910al-48G Switch, revision W.14.49, ROM W.14.04
MTU is set at 1500
No firewall rules in the filter chain
No mangle or NAT loaded or compiled in the kernel.
Bonding on 2 igb gigabit ethernet is activated.
Network traffic was at 700mbit and 900mbit in each instance.
