Hi us...@httpd
As I mentioned in an earlier email, we're running mod_perl on Apache
(2.2) on RHEL, using the prefork MPM. I want to protect my server
against Perl processes that grow much too large, as they can slow or
even freeze the system.
Therefore, I'm using Apache2::Resource, adding the following to
httpd.conf:
PerlModule Apache2::Resource
# set child memory limit to 1000 megabytes
# RLIMIT_AS (address space) will work to limit the size of a process
PerlSetEnv PERL_RLIMIT_AS 1000
PerlChildInitHandler Apache2::Resource
httpd processes die as expected when their VM size reaches 1000 MB.
But here's the problem. After the httpd serving the Request dies, a
new one is created to handle the same request. And so on.
I think this is all done in Apache, as the access log doesn't show
another request from the client. Is this correct?
How can I limit the number of 'retries' of the failing request? Is
there an Apache directive?
And I'm still looking for a way to 'catch' the exception when the
process dies.
Regards
Arthur
