what causes exit signal Segmentation faults?

[chips12]

Linux dual core 4GB
CENTOS 5.9 x86_64 standard – server
WHM 11.36.1 (build 5)
php 5.3.24 dso
apache 2.2.24

I have recently used Easy Apache Update and checking the apache error log see the following exit segmentation faults. I have tried to find what is causing this by switching off the websites being served, in case it is some php script, but these faults still show up, even when all sites are offline and just simple html paintenance pages are only being accessed. I am not sure what else to check, what could be causing these faults. The websites seem to be functioning correctly, so it is odd...

apparently you need to fill out a ticket because they don't know or care to respond.
fill out the ticket or try and rebuild apache paying attention to your selections used to build it.

I am working on this issue as well.

Thanks for the reply. I have also tried rebuilding using easy apache a few times. I am not sure which option maybe causing the problem, from what I have read it may be some module conflicting or something.

I also read it can be caused by a php script, so to make sure that was not it, I stopped all traffic to any php for a while, redirecting all sites to a maintenance html page...still got the exit segmentation faults though, so I dont think it is a php thing...

I am also finding some processes getting stuck and pushing up server load, so I have to manually kill them. That is intermittent and I am not sure if it is related or not.

I suffered this problem after running

pear upgrade

from root shell. In desperation, I restarted Apache and everything worked again fine.
