As I explained, I want to be able to run a second instance of DC through another port to do testing while not interrupting the users using the primary instance in the the regular port. I was instructed to create a second config file with different listen ports and a separate base_dir.
I did so and invoked dc with -c pointing to dovecot2.conf.

Jun 7 10:04:23 mercury mail:info dovecot: Dovecot v1.0.0 starting up

I pointed my client at the non-SSL port, and everything worked fine....until 3 hours later. The client wasn't getting things through, so I checked the syslog on the dc server where I saw rapidly repeating errmsgs:...

Jun 7 12:51:07 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 12:58:55 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 12:58:59 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 12:59:01 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 12:59:05 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist

and many more, then......

Jun 7 13:34:20 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 13:36:30 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 13:36:54 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist

I kill the second instance.....but things don't clear up....rather I now get a different errmsg....which must be from the primary dc instance, since the 2nd instance and all of its children are gone (I checked the ps)

Jun 7 13:39:20 mercury mail:err|error dovecot: login: Authentication process 10 89784 doesn't exist Jun 7 13:40:00 mercury mail:err|error dovecot: imap-login: Can't connect to aut h server at default: Connection refused Jun 7 13:40:06 mercury mail:err|error dovecot: imap-login: Can't connect to aut h server at default: Connection refused Jun 7 13:40:06 mercury mail:err|error dovecot: imap-login: Can't connect to aut h server at default: Connection refused

Finally I do a kill -1 of the primary instance and that cleans things up

Jun 7 13:45:46 mercury mail:warn|warning dovecot: SIGHUP received - reloading configuration

Is there something I'm doing wrong? Have other people run two instances without problem? I tried starting the second instance and killing it immediately thereafter....that wnet OK, but it hasn't been 3 hours yet.
