sendmail reject connection on daemon

[rottereau]

I used the mailsetup for sendmail on the 3 members.Now i have on one member a problem with the load average parameter LA with the message :
sendmail[954536]: rejecting connections on daemon Daemon0: load average: 40
sendmail[954536]: rejecting connections on daemon Daemon0: load average: 41
sendmail[954536]: rejecting connections on daemon Daemon0: load average: 41

Do you know how to stop these messages. Probably i can change the LA parameter in sendmail.cf but can i for example delete a queue message or just identify the message than doesnt want to be sent.
thanks for any suggestion.

Hi,

these files are in /usr/spool/mqueue.

greetings,

Michael

in fact it seems that the queues are not the problem because the number [954536] is not a number of a queue. But i really dont know how to stop this message.

Is it normal that your system reach that load average?

Use mailq -v to identify the message, then delete from /var/spool/mqueue as described before.

Manuell,

954536 is the pid of the sendmail process.
Why not increasing the parameter?

Depending on where that message is being reported, the number in square brackets is usually the process id for the process reporting the message, in this case sendmail, but it seems like a pretty high pid number.

Run the command uptime. It will show you three values for system load average. If any or all of these are in the 40 or higher range, then you have exceeded the default parameter at which sendmail stops receiving mail.

They are found in /var/adm/sendmail/sendmail.cf as:

# load average at which we just queue messages
# The Alpha CPU is fast, so we don't settle for the default.
#O QueueLA=20
Ox20

# load average at which we refuse connections
#O RefuseLA=12
OX12


You can increase these values to something above the load average of your system then restart sendmail, but it will also add to the already high load of the system. Normally sendmail backs off and acts nice by refusing to contribute to a busy system.

thanks, my problem is solved. I put higher values for the LA fields and its oki now.
