[rt-users] High CPU load on RT 3.4.4, Apache2, Fast_CGI

[VTW]

My "standard" config is to run RT in its own user account, with a custom 
installed perl, and apache.  One of my installations is as such:

/home/rt/

rt - installed rt
local-perl - local perl
apache2 - apache2 (see my naming convention yet?)
src - the source files

This system ran fine under Apache 1.3 w/ mod_perl.  I needed to move to 
Apache 2.0 (for LDAP authentication to work, I couldn't get it running 
under 1.3).  I also switched to Fast_CGI because I could not get 
mod_perl working properly .. I keep getting perl module errors.

As soon as I start apache, or soon thereafter, I get 100% cpu usage from 
Apache's fast_cgi ..

It will never drop to 0% cpu, and my machine always reports 1.0 1.0 1.0 
cpu usage.  It seems to get slower and slower and slower until I restart 
Apache (which I am doing every 4 hours at this point).

 From httpd.conf

Other than the 100% cpu problem, this config works fine. 

Does anyone have any ideas what might be causing my 100% cpu load problem?

Thanks!
