Hi all, Sorry but I have been away for a few days and when I came back I found our backbone listserv machine in a very sorry state, an email error sent to me as administrator contained the error attached below. This ends with an "Unspecified error (181)" Can anyone out there provide any enlightenment, I am stumped by what actually happened. Looks like it just had a problem writing a .tmp file and that the severity was informational, however this error appears to have been responsible for causing the machine to reboot due to a bugcheck ???, or at least that's what it said in the event logs. The machine is an NT4 sp6a box with a Pentium II 200, and 192 mb Ram, it is fully patched 1.8d listserv running with LSMTP. Any useful ideas ?
