Package: linux-image-2.6.26-2-amd64
Version: 2.6.26-19lenny2
Followup-For: Bug #559035

Just a 'me too' on the plain kernel version.

Some way along the upgrade path
[UPGRADE] linux-image-2.6.26-2-amd64 2.6.26-17 -> 2.6.26-17lenny2
[UPGRADE] linux-image-2.6.26-2-amd64 2.6.26-17lenny2 -> 2.6.26-19
[UPGRADE] linux-image-2.6.26-2-amd64 2.6.26-19 -> 2.6.26-19lenny1
[UPGRADE] linux-image-2.6.26-2-amd64 2.6.26-19lenny1 -> 2.6.26-19lenny2
I started getting random python segfaults in the log (see log below).
There are no additional trace lines in my log, though.

All of them are from 5 different python cgi scripts out of a bigger
set, and apparently they succeed without segfault most of the time.
Actually the segfaults seem to happen only once in every 10000 or more
tries.

All the scripts do file I/O, but do not use any exotic python modules.

The simplest one I've seen fail is available from:
http://code.google.com/p/migrid/source/browse/trunk/mig/cgi-sid/isjobactive.py


It is a production server, but please inform me if there is anything I
can test without too much down-time.
