Subjecttcp_v4_hash bug ?
Date
I have a Oops in the kernel which say's "tcp_v4_hash: bug, socket state is 1"
can someone explain me what's wrong ?

for those who can understand it here is the log :
(note : I can't use ksymsoops has I only have the compressed image and for now I can't rebuild it !)
maybe someone can help me find what's go wrong, I can do some testing, but as I don't understand what means the
error message...
PS: kernel is a 2.2.17 with dhighen NFS patch running on HPnetserver LPr (NRC scsi module, eepro100 module, SMP box booted with maxcups=1 because of a JVM bug)

Thanks for help
