sendmail rejecting connection

Fadia Almarei — Wed, 07 Jun 2006 01:00:30 GMT

Dear All
I have the following problem when I start senmail
sendmail: rejecting connections on daemon MTA: load average: 50

I want to know the cause of the problem and how to solve it.

Well, the load average is too high! When the load exceeds a certain threshold (50 in your case), sendmail stops accepting connection UNTIL the load drops below the threshold.

Find out why your load is so high!

as stated above, sendmail is rejecting because the current load average is above the accepted threshold. current LA is 50, threshold is in sendmail.cf:

O QueueLA=8
O RefuseLA=12

So to get mail going again, you should investigate, why 50 processes are waiting to get processor time, and get this number down below the thresholds. I suggest you leave the defaults alone, since changing the LA thresholds in such a way, that mail will flow again, will just add to the load, and decrease the performance even more.
