# Apache::Reload - Reload Perl Modules when Changed on Disk PerlModule Apache2::Reload PerlInitHandler Apache2::Reload PerlModule Apache2::RequestRec

I have this enabled but I've found that if I make lots of changes to the perl code Apache just slows to a crawl and I end up bouncing Apache anyway.

I just figured out that there are two layers of caching. One for Perl code and one for static stat data (the data retrieved from DB).

I also just noticed that I can disable caching for DB data right from OTRS's STATS GUI for a certain stat, including static ones. So that's what I want for production, that part of the problem is solved (I hope).

For development, I need to disable caching of Perl code because right now I don't see the effect of any change I make in StateAction.pm's code without restarting Apache. Anyone knows how I can do that?

So in my config file (which is the out of the box one) those settings are already there and enabled. So it is supposed to automatically reload any pm files which change on disk. Steve On 16 November 2012 09:14, Bogdan Iosif wrote:

I just checked my config and my problem appears even though I do have enabled the configs specified by you.

My apache2-httpd.include.conf is unchanged from the one that came "out of the box" with OTRS v3.1.9.

Did you mean that I would have to change this .config file for Apache to trigger Perl module reload or did you mean that it will autodetect changes on .pm / .pl files from OTRS dir?

It's supposed to reload anything in INC, so that would include the OTRS files. Steve On 16 November 2012 11:40, Bogdan Iosif wrote:

Maybe it's only looking in some dirs? I don't know if this is configurable/configured for OTRS.

The file I'm changing is ... \OTRS\Kernel\System\Stats\Static\StateAction.pm
