Morning...
Today, three times so far, as far as I've been able to tell, my new
server 'panic: page fault'd in what seems like sosend(). gdb output
included below (and in PR).
I'm running 2.2.2-RELEASE on the machine, and am curious as to whether
or not this is a known problem with 2.2.2-RELEASE, and will upgrading to
2.2.2-STABLE will fix it?
Also, is there any way of finding out what caused it? It seems strange
to me that its been running problem free for 2+ weeks now, and all of a sudden
I start having problems :(
Don't know if this helps, but my ethernet card is detected as:
vx0 <3COM 3C905 Fast Etherlink XL PCI> rev 0 int a irq 5 on pci0:11
mii[*mii*]: disable 'auto select' with DOS util! address 00:60:97:72:57:bf
