SunOS 5.7 Sendmail Problem

SunOS 5.7 Sendmail Problem

Post by sun_ad.. » Thu, 27 May 1999 04:00:00



I'm having a problem w/ sendmail on a machine running SunOS 5.7.

Sendmail seems to die at random times, and when you start it again, a process
listing shows the following...

    root 16184 15483  0 08:12:12 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 15486 15483  0 08:08:41 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 16376 15483  0 08:13:17 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 16201 15483  0 08:12:26 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 16168 15483  0 08:12:03 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 16281 15483  0 08:12:56 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 16031 15483  0 08:11:49 ?        0:00 /usr/lib/sendmail -bd -q30m
    root 15483     1  0 08:08:40 ?        0:00 /usr/lib/sendmail -bd -q30m

It appears to be running sendmail a whole bunch of times, but when you telnet
to port 25, it responds just fine.  But then hours later, a day later, whatever,
sendmail will not be running anymore, and has to be restarted.

Any idea why it's dying and why it lists so many sendmail processes?  There's
nothing in the logs to explain it.  Thanks!

SunOS 5.7 Sendmail Problem

sendmail forks a new process for every new connection, so it is not unusual
to see multiple processes running, although looking at the times on them it
would appear that something is potentially keeping an SMTP connection open
without closing it.

Are you SURE it's dying, and not self-limiting?
once the machine reaches a certain load, sendmail will stop forking new
jobs, and even allowing new connections.

1. STL map problem on sunOS 5.7, not on sunOS 5.8

I am experiencing a problem in which a hang is occurring while trying
to find a key in a stl map (it is never reaching the null at the end
of the map). When I run the code on a sparc machine with version 5.8
it runs fine. When I run it on 5.7 a hang occurrs. It does not matter
which version I compile on. Has anyone experienced anything like this,
or have any suggestions.
