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. Timo> Thank you in advance !
