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

Thu Dec 17 12:34:57 EST 2015

Hi there!

I have been having the same error after I installed the RT-Extensions
(ActivityReports and CommandByMail). When I disable this extensions on
RT_SiteConfig.pm, this erros has stoped.

I'm still looking for to solve this issue.

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

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.
