[mp2] panic pthread_key_create failed in apache 2.2/mod_perl 2.0.4

Hi,

-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:

I am running a web server configured via cpanel/whm ( Apache/2.2.16 (Unix)
mod_ssl/2.2.16 OpenSSL/0.9.8e-fips-rhel5
mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635
Phusion_Passenger/2.2.15 mod_perl/2.0.4 Perl/v5.8.8 )
with multiple sites hosted, some are ruby-on-rails / passenger sites and one
is Request Tracker - a perl based support
ticket system. RT is the only perl application I am running.

Every so often (about once every two weeks) I get this error in my apache
error log "panic: pthread_key_create failed"
during a process restart, which then brings down apache completely until
another process restart happens or I manually
restart it.

Doing some investigation on google points me at a bug that was fixed in
mod_perl 1.999_21 on January 22, 2005, which is
odd to me since I am running mod_perl 2.0.4.

Here are some posts and whatnot from that bugfix:
