Ok,
I have a system I converted from cgi to mod_perl.
We recently upgraded to mod_perl 2.0 and apache 2.2 on RHL5
I am having a problem. When I refresh a certain page 5 times or about (
it's completely random )
The page renders fine, but in my logs I see that an apache child died
because of a segmentation fault I believe
here is the error or I guess notice message.
[notice] child pid 25946 exit signal Segmentation fault (11) # ? do I
have to worry about this notice ? what we are building will be a live
system.
The best way to get an understanding of what's happening is to get a backtrace
from a core dump.
http://perl.apache.org/docs/2.0/devel/debug/c.html#Getting_the_core_File_Dumped
Will tell you a lot about how to get to a usefull backtrace.
Once you get something ouy of your crash, send it to this list and there
might be a solution to your problem.

I haven't used gdb that much.. but I have attached a core file. Will
you help me examine it's stack frames I can't seem to get a useful
backtrace it doesn't seem llike there are any symbols, but I have not
used this that much before.
Here is the initail message when I ran gdb core core.8130
(no debugging symbols found)
Using host libthread_db library "/lib/libthread_db.so.1".
Core was generated by `/usr/sbin/httpd -DDevSite -DSSL'.
Program terminated with signal 11, Segmentation fault.
#0 0x0051389a in ?? ()
... Ooes this mean that the database has a threading problem?
