For referance the problem i am seeing, is that even
though i have configured a load of modules to be preloaded, they are not being
preloaded, or at least not being shared.
This happened after moving to a new server running the same redhat 9 but with different kernels and glibc's. I'm betting thats where the problem is. In the old server everything was shared for a good while. Has anyone had similar problems with RedHat
9?
It appears to be one of two things;
1. mod_perl is not loading modules before the
fork()'s.
2. fork() is not correctly identifing pages which can be shared. How ever, all the code does appear to be loaded
into the parent apache process its just seperated during the fork.
mod_perl / apache configured with
