Lucky you for being able to get a core dump. That's my next question. :) Based on your output I think the issue is with the php module. Do you use php on your site? Can you disable it to see if that resolves your issue? I'm actually pretty new to all of this myself so apologies if this doesn't help. ________________________________ From: TArak <lifewithqmail@xxxxxxxxx> To: users@xxxxxxxxxxxxxxxx Sent: Tue, April 26, 2011 5:52:07 AM Subject: Apache "child pid 3432 exit signal Segmentation fault (11)" Dear List, I am getting the frequent error in apache.
