Server Crash

[Paul Houselander]

I am running MailScanner on a cobalt box.

Has been running happily for over a week, yesterday the machine fell over, and does so everytime I now start up mailscanner, their are messages (75) in mqueue.in, 

I had signature/spam/custom headers defined in mailscanner.conf so have defaulted back to the original installation, however everytime I start mailscanner, after approx 3-4 mins the machine complains of being out of memory and falls over.

Its a remote machine so takes a bit of time to get someone to go and power cycle it.

When its back up im going to move the messages in mqueue.in into mqueue and see how sendmail copes with them, in the meantime can anyone offer any potential explanations? seems to have got itself into a loop but Im not sure what action ive taken that has caused it. Extract of maillog below.
