I'm afraid I don't know about version specific differences of DBD::mysql
and if the driver can deal with fork() as you expect it to.
But I ran into this problem before. In fact mysql "went away" when
serveral child processes used the same handle AT THE SAME TIME.
fork() does not know about mysql. it makes a copy of a variable which in this
case is a reference to the same mysqld process (?). I think that each process
needs its own connection. Otherwise mysql could not handle concurrent
queries (over the same handle).
