Nonexistent process in Red-hat 4.0

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
I am getting a interesting problem.I have a module build on Red-hat 3.0.I am using Apache2.2 MPM model as Worker.
Now I print the current process id in my logs whenever I get my any request.
In 3.0 the process ids are matching with what exactly the Apache 
launches.But when I move to 4.0 the process id doesn't match at all.Logs are printing the same process id.And if I do a ps -aef|httpd on that process id I get no such process exists.Also if I try to kill that processI get the same statement as "
No such process".But functionality of the process is fine.

Not sure as this is the correct forum or not.If you have come accross this sort of problem please let me know.
Thanks in advance.
