As far as I (and the silent members of #perl) can tell, the Perl Object Environment (Shadowbot's multitasking module) doesn't use fork or threads to run queries with the MySQL object in Shadowbot. So, the bot should only have one connection to the MySQL server at any point. And even if there is one MySQL object being established for each thread, ie each reversion, they would still be destroyed at the end of the revert.

While I don't know much about how the bot works, but as I understand it
is
one continuously running IRC bot. The only situation I can image when the bot is hitting the limit is when
it
establishes a new connection every time it runs a query, which would be
a
Bad Thing (TM). But if that's the case, a better solution (both for the database
server's
and bot's efficiency) would be to create and maintain only one mysql connection for the entire bot's operating time (or one per running
thread).

Nonetheless we cannot deny that it has started acting up since
then. Of
course tightening the MySQL code will help, but ultimately I think
that
realising that the connection limits may need to be a little more
flexible
isn't a bad thing.

That's what has me confused, myself. It shouldn't be creating multiple connection instances.
