attached mail follows:
Hello,
[1.] One line summary of the problem: Kernel OOPS. Machine hanged under heavy load.
[2.] Full description of the problem/report: The computer that is handling our e-mail hanged with an OOPS from which I recovered only the EIP.
[3.] Keywords (i.e., modules, networking, kernel): networking, kernel
[4.] Kernel version (from /proc/version): Linux version 2.4.3-pre4 (root@k) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #1 SMP Tue Mar 13 11:00:08 EET 2001
[5.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt) This is all that I could save:
Unable to handle kernel paging request 86c90cc0 OOPS:000 CPU1: EIP=0010:[<c01f7d08>]
I could not get the stack trace. Next-time I'll log the message on a serial console.
If I read from System.map the address is between:
00000000c01f7b98 T tcp_v4_rcv 00000000c01f81b0 t __tcp_v4_rehash

[7.7.] Other information that might be relevant to the problem (please look in /proc and include all information that you think to be relevant): This is a very loaded server running lots of apache processes and sendmail.
