:New submission from Peter Avalos <pavalos at theshell.com>:
:Here's a panic I'm getting with some pretty serious network (www) load, then
:doing a netstat -an:
:Unread portion of the kernel message buffer:
:panic: m_copydata, negative off -1
:mp_lock = 00000000; cpuid = 0; lapic.id = 00000000
:boot() called on cpu#0
:syncing disks... 5
Woa. You mean the panic occurs only when you do the netstat -an command
under heavy network load? It doesn't happen any other time?
This is a really odd crash. Somehow tp->snd_nxt has become less
then tp->snd_una, causing 'off' to be calculated as -1.
