pradeep, your report is incomplete. Please read:
http://perl.apache.org/bugs/ and try again.

Any difference if you do 'httpd -k graceful' instead? I think Apache2 may 
not quite work with this kill thing.

That trace is incomplete, you need to rebuild perl and mod_perl with debug 
symbols as explained at the URL quoted at the top of this email. But first 
see if my suggestion to use 'httpd -k graceful' works for you.
