I have a problem with sendmail-5.65+IDA-1.4.2 running on
Sun 4/390 (SunOS 4.1). I got it running
(aliases database and so on worked well), but it crashed the Sun few
times (three times) during the night. We have had the same sendmail
running on Sun 3/60 (SunOS 4.03) about one month and it seems to work
fine.
Does anybody has any idea why it crashed the system ?
Thank you in advance !

Was it a 'data fault' crash? If so, you may have run into the PMEG bug.
You can either get the patch from Sun, or upgrade to SunOS 4.1.1.
