I've got an existing production system which I've built and maintained over the past 3 years - I've never had a problem with mod_perl until about 4 months ago.
During that time I built a new module - PostBlotter.pm, which was not preloaded in startup.pl (I don't typically preload most of our periphery applications). We have about 90% of our 20 modules in a non-preload state, and have never had a problem. However, with this project, PostBlotter and ONLY PostBlotter began exhibiting random (maybe 4 out of 10 requests?) 500 errors - with an error log note of: Undefined subroutine &Apache::MuniCenter::MarkupMatrix::PostBlotter::handler called. And no further information. The cause of this could not be determined, and it was found that setting it to preload in startup.pl completely resolved the problem. Now, a few months later, I've written yet another not-for-preload, periphery process, and I'm seeing the exact same problem, again about 4 out of 10 times: [Mon Nov 17 10:46:43 2003] [error] Undefined subroutine &Apache::MuniCenter::MarkupMatrix::TaxSwap::handler called. Unfortunately, preloading this was not possible - we found that Inline::Java, which we load in for various bond calculation routines, does not behave properly when preloaded, and causes the entire mod_perl system to be unstable; consequently we can't preload this module. At this point I need to know WHY mod_perl randomly can't find the handler, which is properly written, runs through perl -c cleanly, under strict and warnings, and has a 1; at the bottom. Are there any known issues that could cause this? Any easy way to produce a trace of where Apache is looking and what's happening (preferably not a recompile of apache - a trace perl module I can load would be better). This problem exhibits across my development, test/integration, staging, and production environments so it's not a single box issue.
