Ok, I've had the chance to experiment a bit more with
BSD::Resource::setrlimit function. After I sent my last message to the
mailing list, I again accessed the Apache::Status Resource Limits page,
and this time RLIMIT_DATA was unset. I reloaded the page several times,
and the behavior seemed sporadic -- sometimes RLIMIT_DATA was set and
sometimes not. I added a line of code to the Apache::Resource module to
print out the PID before the resource limits table, and it seems that
only one or two of the processes have RLIMIT_DATA set. These are child
processes, too.
I got this behavior when I put my setrlimit-calling module as a
PerlFixupHanlder or as a PerlChildInitHandler.
Can anyone tell me how to consistently set RLIMIT_DATA for all httpd
processes?
Thanks.
