 New Comment:

Ok, so that sort of makes sense that there is a connection pool per worker in apache, but the bug
noted in the comment from "[2013-04-02 16:47 UTC]" still exists that emits an error about
the connection being dead even though one is returned after being reconnected.

Indeed, the persistent connections and the stats are stored
separately for each worker process (or thread), so in a typical
scenario with multiple workers, pooling may not work as expected.
The respective documentation[1] should clarify that; the note
about ODBC connection pooling already hints at this, but is not
general enough.

maybe you don't understand that each worker process has it's own persistent connection and
that every client connection to the Webserver may be handled by a different worker

so in the reality you have sooner or later the number of max worker processes mysql connections and
hence the concept of persistent database connections is idiotic

Why is it I received an email that said I could re-open the case if the problem still exists, yet
when I do (which the correct password), it says "you are not allowed to change a ticket to that
state" (or something like that
