[otrs] Intermittent 500 errors with OTRS 2.1.5 under Debian ISPConfig

[Reda Sadki]

I've installed OTRS and I'm trying to configure the admin panels.
However, I get intermittent 500 errors, and OTRS is very, very slow --
usually between 5 and 20 seconds between each click!

I've documented this extensively on howtoforge.com, but no one's been
able to help:

I know that I first need to fix the script errors, but I'm also very
concerned about the performance.

Thanks for your help
