Hello List,
I reported frequently system lockups today.
Now after some playing around (cause I don't know anything about kernel
debugging - Thanks to Mark Hahn for the tipps)
I found a way to reproduce the lock and to get the OOPS.
Dan Kegel told me after the last post that only kernels built from the
kernel.org sources can be supported
by this list. I now used the 2.4.20-2.25smp kernel from RawHide. And I
didn't build a kernel from kernel.org.
O.K. here's the deal:
The OOPS below looks like spanish to me but for the hackers the thing could
be very clear.
So if you think that is a common kernel issue please help. Otherwise I'll
report to RedHat immediately.
Scenario:
2.4.20-2.25smp from RawHide
Doing a rsync from the crashing host _to_ another host over a 1000 Mbit 3com
(TG3).
The rsynced files include bigger files with about 1.5 gigs.
Heartbeat runs.
Below are the OOPS.
Please CC to dk@webcluster.at if you are wanting to help.
Thanks a lot
Daniel Khan

Can I ask how you reproduced this? I've got several systems with TG3's
and they only get lockups during network backups.

httpd session on the host which has big logfiles to get them changed.
Starting rsync to sync the logfiles and other stuff to the backup host.
Sometimes I have to retry 2-3 times but it crashes very reliable.
It's quite the same as the network backups you mentioning.

We use rsync to do our backups. I've been getting lines in my backup
server kernel and dmesg like this:
TCP: Treason uncloaked! Peer 10.1.1.40:37859/873 shrinks window
2430745930:2430747378. Repaired.
TCP: Treason uncloaked! Peer 10.1.1.40:37859/873 shrinks window
2430745930:2430747378. Repaired.
I was able to successfully reproduce this error in a test setup, but not
the crashes. I'm curious if maybe I just start up too many instances of
rsync and see what happens.
Any particular method or size of files, etc, in reproducing this would
be greatly beneficial. TIA

Here is the command
/usr/local/bin/nice-rsync --rsync-path=/usr/local/bin/nice-rsync --whole-fil
e -auq --delete /var/log/httpd/ 10.1.0.212:/var/log/httpd
/usr/local/bin/nice-rsync :
#!/bin/sh
exec nice -n 19 rsync $*
Best regards

Kewl. Thanks, I will try this out tomorrow and let you know.
