Description of problem:
This server (Dell PowerEdge 300 Bi-PIII 800 1GB Memory) turned without 
problem on 2.2.19-6.2.1 SMP since June 10.
And since July 3 we had 2 violent crash.

Here's the log for the 07/03:

How reproducible:
Didn't try


Additional info:

For information, this server is a samba server for approximately 450
stations, so the number of smbd process is approximately 450 smbd (about 
2MB memory for each smbd process) and there's a big activity.

Comment 1 Arjan van de Ven 2001-07-05 12:13:28 UTC

Is this machine doing NFS as well ?

Comment 2 Le Tanou Jerome 2001-07-05 12:23:41 UTC

Created attachment 22747 [details]
dmesg

Comment 3 Le Tanou Jerome 2001-07-05 12:25:10 UTC

No, we don't use NFS.
It only do samba (2.0.9) server (nmbd smbd) and printer server.

There's a RAID subsystem of 7x36Go RAID 5 with 1x36GO spare

Comment 4 Le Tanou Jerome 2001-07-05 16:19:50 UTC

I have just seen that there are new packages kernel-*-2.2.19-6.2.7 dated June 25.

What are the corrections brought with regard to the old packages kernel-*-2.2.19-6.2.1 dated April 25 ?

There is no indication on your site : http://www.redhat.com/support/errata/rh62-errata-general.html

Comment 5 Arjan van de Ven 2001-07-05 17:15:42 UTC

I have no idea why the page isn't updated; I'll email the person responsible for
that page.

The changes are:
* Fixed ibcs
* reverted new xircom carbus driver as new one didn't work for everybody
* VPN masquerading code added
* Fixed race in NFS layer

Comment 6 Le Tanou Jerome 2001-07-16 09:29:31 UTC

On July 5 we replaced all the memory and recompiled the kernel from packages 2.2.19-6.2.7.
And since this date, we have no more crash. We think of a defective memory, so we close this incident which was not apparently a bug.

Thanks.
