Even if each concurrent connection averages only one sort (and they can use more) that's 3600MB ... roughly 1.5 times your *total* RAM, leaving out RAM for Apache, postmaster, shared buffers, etc. I strongly suggest that you either decrease your total connections or your sort_mem, or both. -- Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
