Will do that and let you know.
But I added some loging, so that when request comes PID is printed, and some request

Interestingly if I fire "MaxClients" no. of requests these old processes goes away.

I am on Solaris 8 and unfortunately using 1st GA release of 2.0 i.e 2.0.35. May be the
bug you are refering to was there 2.0.35, is this right ? if so then I need to patch
my source with fix.
