Bug#553503: Confirmed here as well, suspect kernel interaction

[Christian Balzer]

Package: exim4
Version: 4.69-9
Followup-For: Bug #553503

I have been seeing this for a while, esp. when stress testing 2 new
mailbox servers here. There seem to be no lost mails and the segfault
below happened during a queue run (-q2m) on an pretty idle box, with no
mails being delivered for hours beforehand. Which pretty much rules out
corrupted database files. Seen this with both heavy and light deamon
flavors. No problems on the remaining Etch machines.

My architecture is as with the other 2 reporters amd64 (x86_64) on 2-8
core SMP machines, all running Lenny.  
I use custom kernels, predominantly 2.6.27.latest or 2.6.latest. 
However one decently busy machine running a 2.6.24.7 kernel NEVER
exhibited this problem, leading me to suspect that there some interaction
with a kernel feature after 2.6.24 and exim 4.69-9.

Regards,

Christian
