sorry, what i meant was what script was accessed by the httpd process.
That's the first problem, locating what set of scripts(modules) it can
be and after that start looking...

ok, i'll look into that. I've been using RLimitMEM and RLimitCPU in
httpd.conf:
RLimitMEM 15728640 15728640
RLimitCPU 600 600
and haven't got them to work very good:
10314 httpd 13 0 67824 66M 5572 R 0 17.9 13.1 4:19 httpd
10313 httpd 13 0 69984 68M 5580 R 0 17.7 13.5 4:33 httpd
but i guess that's fairly OT on the mod_perl list.
Thanks for the quick reply!
