--- Comment #21 from Karen Ezzo <karen.ezzo@yahoo.com> 2012-01-17 20:58:21 UTC ---
I am experiencing a very similar problem but I am on apache 2.2.17. I have been
seeing these messages in the error_log:
[Thu Jan 12 09:23:12 2012] [notice] child pid 16000 exit signal Segmentation
fault (11), possible coredump in /usr/local/apache2/

I am relatively new to troubleshooting apache but did manage to run a coredump
file thru gdb. However, my output is different than previous posts:

In searching for this last "Backtrace stopped..." message, i found this apache
bug (48030). Can anyone tell me if this is or is not the same problem?  If so,
is the above mentioned patch applicable since I am at apache 2.2.17?  If not,
any further suggestions would be much appreciated!

Karen
