I had a similar problem once, not as extreme as the one you describe but the symptoms where the same. A few times a day one of our servers reported load averages at about 5.0-5.5. By the time I got there (30 second run to the serverroom) the server was always back to almost idle, avg around 0.2-0.5. The only thing that was different in this compared to most of the other servers was the nic. Since the onboard nic died we had to replace it with a low profile PCI nic. I cant remember the exact make and model, but it was probably something cheap from the nearest computer store. Using systat I noticed that during the bursts of high loads the number of interrupts on the nic went skyhigh. We replaced the nic with a more wellknown brand, and the server flatlined its load average. Its still doing exactly the same tasks but rarely goes above 0.1. -- R ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

No, we aren't running razor, just the base spamassassin without razor, DCC, or Pyzor. On Mon, 28 Jul 2003, Max Clark wrote: > Are you running razor?

Are you running razor? Something that I have experienced with spamassassin is if you have external network checks enabled and spamassassin cannot connect to the resource uptime goes crazy.

It could be disk I/O issues or memory. Also you want to track which processes are just starting. Do a google for freebsd system accouting to see if that can be turned on.
