I have the issue when using Apache on CentOS 5.2

[root at rt ~]# uname -a
Linux rt 2.6.18-ovz028stab039.1-smp #1 SMP Tue Jul 24 12:12:48 MSD  
2007 i686 i686 i386 GNU/Linux

httpd-2.2.3-11.el5_1.centos.3
mod_perl-2.0.2-6.3.el5

DBI is up to date (1.607).
DBD::mysql is up to date (4.008).

I have worked around it for now by serving the pages with lighttpd  
with FastCGI.
