I am struggling with occasional crashes of my SuSE 9.0 pro server that
seem to be getting more frequent. I have been trying various google
searches for a while, but so far haven't come up with many clues. The
setup is an Athlon XP 1800+ running a clean install of SuSE 9.0. I have
LDAP, Cyrus, Postfix, Apache2 and Samba running as I use this mainly for
email and file serving to my XP workstation. All these are the standard
versions supplied with the DVD version, except that the kernel has been
updated using YOU. The disk is partitioned using the YaST partitioner
and all partitions are Ext3 and I'm using ACL's. The machine has a
single 160Gb ultra-ATA hard disk with a number of different partitions
including 512M swap space (physical RAM is also 512M).
Most often I come down in the morning to find the machine completely
locked solid, I can't get to a console using Ctrl/Alt/Fx and the network
is dead (doesn't respond to ping). After rebooting I have found entries
indicating that there is activity across the Samba network connection,
which I have traced to a nightly backup that I run on the XP workstation
(I'm currently migrating this to the server). I stopped the backup,
which helped to keep the server up over-night, but when I am doing
things that make heavy use of the server it tends to fail still. When I
am working with it I can sometimes catch it before it fails completely
and recover use of the system simply by restarting the network (~#
rcnework restart).
I have tried to get a better idea of what is happening by increasing the
logging level on Samba (level 1) and LDAP (level 384) as these seemed
most active about the times of failure. When I did this logging I ended
up with >45M of log data in a few hours, the vast majority of which is
just connect information from the LDAP server. I have turned off the
LDAP log and left the samba log running at level 1. After the last
crash I found the following entries in the log.

I found a reference to this error message that indicated that the
entries
oplocks = no
level2 oplocks = no
kernel oplocks = no
would help, though it was quite old and referred to an earlier version
of Samba. I tried the settings anyway, but with little change. I am
now seeing errors like this.

[ big snip ] this happened to me as well. My cure was: online update. HTH, Martin
Thanks, but I have been keeping up with updates. Ran the latest today, but I don't expect any improvement. At the moment I'm more inclined to think that updating on-line constantly is not necessarily the best thing to do.

Having switched off all the non-essential peripherals on the motherboard and set DMA off for the hard-drive I have finally worked out the problem (I think). The system had two network cards, one on the motherboard (nVidia nforce2 chipset) and a 3Com 3C5xx series. I was using the 3C because when I installed the system SuSE failed to setup the nForce. Now I've setup the nForce and switched to it and managed to move enough data across the network to burn the DVD I have been trying to do for the last 3 days.
