On an i386 (newly installed within the last two weeks), where
the kernel and userland has been sup'ed and rebuilt on 13 Nov,
we saw a panic this morning:
cg=15 irotor=60 fs=/usr
panic: ffs_nodeallocg: map corrupt
_ffs_hashalloc(f084e500,f,6d53,81a4,f019b828) + 0x57
_ffs_valloc(f2e33db4,f2e33e0c,f2e33e20,f2e33ee0,25) + 89
_ufs_makeinode(81a4,f0853200,f2e33ef0,f3e33f04,f2e33e84) + 78
_ufs_create(f2e33e0c) + 24
Does this ring any bells? Any suggestions or explanations ?
The machine died during the weekend, probably about 22:08
Sunday evening, and its main task has been to run the perl
based mrtg application, i.e. retrieving some SNMP statistics
from a bunch of routers.
The above mentioned backtrace was written down on a piece of
paper and then keyed into this message -- no guarantees for
Also I regret to say that I do not have a dump (DDB's reboot
did reboot, but produced no dump, I'll have to see how to
get the dump, if it happens again).
