Mark, Many Non-Centos originated packages create directories in /var/run as 
part of the install, and expect them to still exist after a reboot.

They then fail when starting the service because they're trying to create a 
PID / Lock file in a directory that no longer exists.  This problem has been 
around ever since /var/run was moved to tmpfs.

Unfortunately, sometimes we have to use packages other than the official 
Centos ones, usually as in this case because we need newer versions.

There is a solution that saves /var/run to disk at shutdown and restores it at 
bootup but I can't remember what it is.
