Description
George
2004-12-08 19:28:33 UTC
Looks like memory corruption, specifically ASCII characters "GET " (or maybe " TEG", depending on byte gender) in the "sk_reclen" field of an "svc_sock" structure as detected by svc_tcp_recvfrom(). Could you please provide the output of "lsmod" and information about the network driver and hardware in use on the machine(s) producing these error messages? It is a dell PE 2650 with dual processors. HT is enabled. network driver is tg3.
Thanks.
