Hello.

Yesterday we had a strange behaviour in our production courier servers. At 15:12 there was a normal "courierd: completed,id=xxx" message. It was the last completed during 3 hours. After that message, there were a lot of "courieresmtpd: started,ip=[::xxx" incoming messages which caused the queue to grow. There was also this message: "courierd: Waiting. shutdown time=none, wakeup time=none, queuedelivering=306, inprogress=1" repetead always with the same values for the 3 hours.

Past 3 hours we detected that there were no outgoing mails neither local delivered mails. We made a "courier restart" and courier began to deliver messages and empty the queue.

The main courierd process, the one owned by root, was running all the time (because it is several weeks old).

What has happened? Any ideas?

As info, we make a "courier restart" everytime we set up a new hosteddomain through our provisioning system. Maybe something related with this restart (quite frequent, I have to say) ?

Indeed we have two balanced servers and both had the same problem, more or less at the same time.

Thanks for your help.

Regards, Raúl.
