I am using SuSE 10.1 and dovecot version 0.99.14-5.

After dovecot has been up and running for a while (1 month or so), it tends to get hung up and unresponsive. I do a "ps" and I have a whole host of defunct processes.

To restore service, I have to manually kill all dovecot processes and start it up again.

Is this a symptom of my version or my configuration?

Are you using PAM? It probably has something to do with it. In any case since you're using 0.99 version, I'd just suggest upgrading to 1.0rc. It probably has already fixed the problem.

Yes, I am using PAM. Why do you ask and what is your theory?

Yes, I probably do need to upgrade. I just hate to go outside of my distribution's packages. :(

Thanks for the help,

Each PAM lookup creates a new dovecot-auth process, but I don't really know why they would be left in defunct-state. Those defunct processes are cleaned up when the main dovecot-auth process calls waitpid() function, but that's done every second..

Understood .. thanks ..

Was this ever a problem with any of the prior releases?

Thanks,

I don't remember that far back anymore (0.99.14 was released 1,5 years ago), but I do remember that I haven't seen anyone complain about this with 1.0rc releases. :)

Understood .. Thanks ...
