[rt-users] High loads on Apache (probably) due to Perl errors in the logfile

[raymond.teunissen at kpn.com]

Hi,

I am running RT 4.2.12 on a RHEL system. RT was installed a couple of weeks ago, and since a couple of days i noticed the loads on Apache were very high. When i check the errorlogs of apache, it shows me a lot of Perl errors. I pasted some snippets below. I searched in the wiki and on the internet, but there isn't anything helpful i have been able to find. The fact that i can't read Perl isn't really helping as well ;) Can somebody give me a clue where to look for in this case? It tells me some values haven't been initialized, but I can't seem to find out what those values are for, and why they aren't being initialized.
