Symptoms

Sendmail refuses to accept mail when machines load average is high.

By default, sendmail (All versions) will refuse mail connections

when load average rises above 12. Load average can be seen with the

unix command "/usr/bin/uptime".

# uptime

11:32am up 1 day(s), 23:13, 1 user, load average: 0.07, 0.08, 0.09

Where:

0.07 = 1 minute
0.08 = 5 minutes
0.09 = 15 minutes

This can be a problem with multiprocessor machines where load averages
can reach in the high teens without any problem in processing performance.
