I'd look into solving this problem first as I suspect it produces the
other "Not a CODE reference" fatal error.

The above error means RT's connection to your MySQL server is being
dropped and it can't reconnect.  You'll need to tell the list more about
your setup (apache conf, RT conf, database setup, etc) for anyone to
hazard a guess why.
