Random NFS panics in OS5

Random NFS panics in OS5

Post by Chud » Wed, 08 Nov 1995 04:00:00



Has anyone heard about the planned fix for the panics in OS5? It happens on
one site of ours about once every two days, and is unrelated to usage as
near as I can tell.

It's been on ftp.sco.com:/SLS for 22 weeks.  oss410.  It's related to
usage: happens when DOS clients are rebooted without first unmounting
their NFS mounts from the server.

Random NFS panics in OS5

Post by Michael B Garrett - Chudy » Sat, 11 Nov 1995 04:00:00


Hi, Bela. We got the 5.0.0d SLS un CDROM about 2 weeks ago, installed it,
and it didn't seem to help. If anything, the panic problem got worse.

From the usage (DOS NFS clients rebooting without unmounting) I don't think
this is the same problem. Is there another source of seemingly-random panics?

We _are_ using MPX on an ALR QSMP4 with 256MB ram, and I remember seeing
something about MPX-related panics, but can't find a ,emtion of it in the
SLS docs or the online stuff.

Thanks for your help-

1. DOS NFS panics OS5

When I use Wollongong's Pathway TCP and NFS software on a DOS PC to mount
an SCO Release 5 filesystem, the first time, it works.  But if I reboot
the DOS PC and try and do the mount command again it causes SCO to panic.

This is what I get on the console:
------------------------------------------------------------
Unexpected trap in kernel mode:

PANIC: k_trap - Kernel mode trap type 0x0000000E

Trying to dump 8095 pages to dumpdev . . .

6144 pages dumped
------------------------------------------------------------

I tried it all over again and got the same message as above, except the
"ebx" changed to 0xF08332C0.

I then rebooted the system into single-user mode and entered the command:
/etc/crash -d /dev/swap -w /tmp/crash.out

and I got:
Read error on page table entry at 0x1ea4ff0:No such device or address (error 6)

This is what hwconfig -h gives me:
