[rt-users] RT 4.0.2 too much CPU hungry !

[Bart]

Difficult to say.

We run RT 4.0.2 on a Debian 6 environment as well (manual installation,
manual perl dependency installation via cpan, etc.)

The only thing I see in your posted config is an error in the way your
plugins are included:


Set( @Plugins, qw(RT::Extension::JSGantt RTx::Calendar) );
Set( @Plugins, qw(RT::Authen::ExternalAuth) );

Should become:

Set(@Plugins, (qw(RT::Extension::JSGantt RTx::Calendar
RT::Authen::ExternalAuth)));

As example, this is how our plugin line is displayed:

Set(@Plugins, (qw(RT::Extension::SLA RT::Extension::HistoryFilter
RT::Extension::ResetPassword RT::Extension::MergeUsers)));

I have no clue if this is the error but the way I see it you should edit it
to match the syntax (as displayed in the comments inside the
RT_SiteConfig.pm).

Did you experience the same issues during testing?
