Package: apache2.2-common
Version: 2.2.11-3
Severity: normal


I'm using this apache2 instance to run OTRS.
OTRS (see http://www.otrs.org) runs just fine UP TO THE POINT where I activate Apache::DBI. 
Once I activated that, apache will crash with signal 11 -- sporadically.

Deactivating Apache::DBI makes the crash disappear. My workaround is to not use Apache::DBI (obviously!)

The core dump gives me the following backtrace:

This crash is with apache2-mpm-worker
I also got crashes  with apache2-mpm-event
Right now I'm trying with apache2-mpm-prefork

this is fixed by libdbd-mysql-perl/4.007-1+lenny1 included in the 
5.0.4 point rlease, and by libdbd-mysql-perl/4.011-1, which has been 
in squeeze/sid for some time.
