Nope. Same problem even with that option turned off.

As much as I trust Linux (IMHO, better than anything to come out of Redmond, yet not quite Solaris yet), 143 days uptime has me wondering if a reboot might be in order...

When I get to a reboot, I'm just out of ideas...

Could there be other tables I need to "optimize?" I'm still a little light on the lingo with mysql, but could there be a corrupt index or could there be any other problem that's index related? I'm just not used to only seeing one connection to a db bring down an entire app like this.

If I'm reading this correctly, ubb makes only one connection to the db, and then runs all of it's queries through that single connection. Right? Otherwise, somehow, some of the queries/connections are not being reported by "show processlist;"
