CPU EXCEPTION

Dear all,

for about one week there are entries like the attached one in the error
log on our machine, one for every mail delivery on this machine it seems,
because there is apparently almost perfect synchronisation between the
mail.log entries and the error log entries. I have installed sendmail
5.67b8+/IDA-1.5 at the beginning of February without any problems and it
worked fine for three weeks, then suddenly the error log entries started.

uname -a: OSF1 mail1.cern.ch V3.0 358.78 alpha
cpu: DEC2100
The question of the significance of CPU EXCEPTION errors has already
been asked several times, but I have not seen any relevant answers.

Looking forward to learn the cause of the problem,
