>Synopsis: Freeze of network router running OpenBSD 5.8-stable
>Category: system
>Environment:
System : OpenBSD 5.8
Details : OpenBSD 5.8 (GENERIC.MP) #1: Sun Nov 8 10:07:44 EST
2015
r...@office.prcsllc.com:
/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Machine tends to freeze (but not panic) after several days of light
traffic, and after only hours of heavy traffic. ddb allows recovery of
trace, ps & show register, but "boot dump" leads to a hard freeze where
BREAK from ddb does nothing. This has happened multiple times. There were
no similar crashes with 5.7 or previous OpenBSD versions.
ddb output from one freeze, with trace, & show register. This is followed
by output from another freeze, with trace and show register and also ps.
