Hello all,

I have several weeks with this problem and its driving me nuts.
At random time of the day SMTP fails to start sendmail process, and no one can send emails until do the following steps:

-service sendmail stop
-omoff -d 0 smtpd
-omon smtpd
-service sendmail start

This process restores normality to the server, but I cannot estimate when it will happen again or why it happens... This repeats average 8 times a day, random! The only way to detect it right now is when someone tries to send an email through Thundermail, which gives the user a popup windows with a message saying that "Failed start sendmail process".

Looking at ~scalix/logs/fatal we have a lot of this:

Set up smtpd debugging, and you can see what it's doing when it stalls.

Put:

Code: Select all

DEBUG_LOG=TRUE

in the /var/opt/scalix/<xx>/s/sys/smtpd.cfg file and restart the SMTP relay:

Code: Select all

# omoff -d 0 -w smtpd; omon -a smtpd
