Kernel assertion failures
Hi.
One of our servers started getting repeated errors like the one below:
Feb 7 02:39:03 xxx kernel: KERNEL: assertion (newsk->state !=
TCP_SYN_RECV) failed at tcp.c(2229)
Feb 7 02:39:03 xxx kernel: KERNEL: assertion
((1<<sk2->state)&(TCPF_ESTABLISHED|TCPF_CLOSE_WAIT|TCPF_CLOSE)) failed at
af_inet.c(689)
Any ideas why? Please cc response to my address.
Sys info below.
Kind regards,
Lucian Kafka
