Re: horrible memory consumption
have a look at the Apache::Status in the cvs tree, there are hooks into B::TerseSize which is used to measure Perl memory usage.

I have a server that starts with acceptable JT numbers, but after a while it turns into this It would probably be best if you started by reading through the performance tuning guide and Stas' mod_perl guide on how to reduce memory consumption. Basically, when you have complex mod_perl operations going in, you want to offload non-mod_perl related tasks (images, static content) to other servers.
Re: horrible memory consumption
Is there a way I can find out where all this RAM is being used. Or does anyone have any suggestions (besides limiting the MaxRequestsPerChild) If anyone knows how to figure out shared vs not shared memory in a process on Linux, I'd be interested in that too...and it sounds like Jason could benefit from the info as well. I know that Apache::Gtop can be used for mod_perl from reading The Guide (thanks Stas!) but I'm interested in finding out these numbers for other non-mod_perl binaries too (such as an apache+mod_proxy binary). Also if anyone has any good pointers to info on dynamic linking and libraries (again, oriented somewhat towards Linux), I've yet to see anything that's explained things sufficiently to me yet. Thanks. GTop (not Apache::Gtop) is written by Doug, not me :) So the credits go to Doug. What you are talking about is Apache::VMonitor which shows you almost everything the top(1) does and much more. You can monitor the apache/mod_perl processes and any other non-mod_perl processes as well. When you click on the process id you get lots of information about it, including memory maps a sizes of the loaded libs. This all of course uses GTop, which in turn uses libgtop from the GNOME project and lately reported to be ported to new platforms as well.

Re: horrible memory consumption
check out the following sections in the guide: http://perl.apache.org/guide/performance.html#Memory_leakage http://perl.apache.org/guide/debug.html#How_can_I_find_if_my_mod_perl_sc http://perl.apache.org/guide/performance.html#Limiting_the_resources_used_by_h http://perl.apache.org/guide/performance.html#Tuning_the_Apache_s_configuratio this ought to get you off to a good start. cliff rayman genwax.com Jason Terry wrote: Is there a way I can tell where my memory usage is going in an Apache child?
