Hello All,

 

                I have compiled Apache 1.3.41 + mod_perl + mod_jk + modssl.Apache child processes are crashing very very frequently and the error.log is getting filled up with the following message

I have compiled Apache with -g option to get the symbols loaded,but unfortunately nothing comes up in stack trace.

 

Any thoughts to solve the issue?

Thanks in Advance,
