Hello all,
We're running into regular panics on our webserver after upgrading
from 4.x to 6.2-stable:
Hi Again,
The panics keep happening, so I'm trying alternate kernel setups. This is a
trace of a panic on a default SMP kernel with debugging symbols.
I'm At a loss on how to progress at this point, perhaps someone can help me
please?

Is this perl derived from ports? And if so, did you rebuild it after you
upgraded to 6.2? Or is maybe FreeBSD 4.x binary compatibility missing from
your kernel?
Hi Chris,
Thanks for your reply; The upgrade i'm talking about is just a term
describing that we switched from FreeBSD 4.10 to 6.2. Its new hardware; its
hardware on which FreeBSD 4.10 will not run.
So in effect its not an upgrade, though the symptoms did not show on
apache-1.3.37 + nfsmounted homepages under FreeBSD 4.10.
If perl would be the problem, the OS shouldn't panic IMHO. Perl in this case
is writing a fairly large guestbook file (eg. 2 Mb), and does this through
perls own:
open(BOOK, "+<$file") or die;
This $file is located on an NFS mounted filesystem. It'll get read and
written.
The NFS filesystem is mounted with "rw,nosuid,intr,bg,resvport,nfsv3". I
have tried mounting without intr, but panics keep happening. The NFS server
is a Netapp filer.
This is a production environment, so I can't go updating to the latest
current.
Kai
Just a me too, however I seem to get these crashes from random applications.
See my last post for back traces.
Tom
