>Description:
The system paniced with a page fault after crashed nfs server came
up. It generated a dump available in
ftp://ftp.clinet.fi/pub/FreeBSD/crashdumps/{kernel,vmcore,kgdb-log}.0.gz
Unfortunately I kgdb isn't too informative about the dump:
hsu#katiska.clinet.fi Tue 4: kgdb kernel.0 vmcore.0
Reading symbol data from /usr/local/ftp/pub/FreeBSD/crashdumps/kernel.0...done.
(kgdb) core vmcore.0
IdlePTD 257000
panic: page fault
kernel symbol `dumppcb' not found.
(kgdb) up
No inferior or core file.
(kgdb) bt
(kgdb) quit
hsu#katiska.clinet.fi Tue 5:
Any ideas?
(FreeBSD 1.1.5.1 also panics similarly after nfs server comes up,
did someone import something from old tree? :-).
>How-To-Repeat:
This is the first time this happened, so I don't know for sure
if this is repeatable. My environment is too much production
environment to try it out by intentionally crashing nfs servers :-(
>Fix:
It probably would help if someone finds out how to read this kernel
dump?
