Well, it didn't fix my problem. I'm guessing that the problem I have might possibly be something to do with bad hardware. (We have about 10 similarly configured boxes and this is the only one we're having problems with - although the workload is not the same on any two boxes). I'm going to start replacing hardware until the problem goes away. (Fingers crossed). Jason Thomson wrote: > Sorry to reply to my own message (should have checked first).
