There are .lst files in the spool directory when the processor is maxing out. They disappeer at a steady rate during the duration of the problem. When the problem is over, there are no more .lst files.
Please keep in mind that this mailing list is only the most obvious and repeatable cause of the processor problems. The processor will go to 100% at other times for between 1 to 20 seconds. During those times webmail or pop might be using 50%+ of the processor. Ted ----------------------------- ----- Original Message ----- From: "R.
