Podz, the host can probably say very little apart from which queries still ‘hang’. As for the reason, it’s hard to tell as you can’t decipher what is actually running. It doesn’t seem like the processes devour any resources (they fall under the ‘sleep’ category). Nontheless, I wonder what spawns this. It might need some experimentation on the OP’s side — seeing what actions trigger an instantiation of such a process (this might require root access).
A clean install might be worthwhile although I doubt the OP has changed anything in terms of code. Could it be something in the database that mySQL or WordPress cannot handle gracefully? I doubt it.
