[Dovecot] [Fwd: mulitple instance run problem]

[Stewart Dean]

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 12:59:05 mercury mail:err|error dovecot: login: Authentication process 10
89784 doesn't exist

and many more, then......

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.
