Hello,
we're experiencing repeated 4.0-C (as of today, something around 12:00
GMT, 1999-03-16) ufs_dirbad() panics, which are the
following (below), which usually occur when squid is running. The box
doesn't have ccd, nor vinum nor anything fancy in it's config, no SMP either.
Squid's spool is hardware (IFT3102) RAID1, 2x9gb (i.e. 4 disks):
/var/crash# gdb -k kernel.1 vmcore.1
