It has Apache running for webmail and qmail is the email server. It is using the xl0 driver for the built-in ethernet card. In searching for this error I found some suggestions that it was kernel related and others said it was the driver for the NIC. Still others said it was just a lack of memory issue. Can someone shed some light on this for me please? Jon
