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?
