[Dovecot] [Fwd: mulitple instance run problem]

9:44 p.m.

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:...

and many more, then......

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)

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.

Hi Stewart, i'm veeeeeery new and noob about doveccot so i suppose a solution or where is the problem. i think the problem is auth daemon....

3671 ? Ss 0:00 /usr/local/sbin/dovecot 3672 ? S 0:00 dovecot-auth 5756 ? S 0:00 dovecot-auth -w u can see dovecot start dovecot and dovecot-auth.

The realy problem u can have is with dovecot-auth because all 2 istance use the same port(socket) for the login.

i don't know how to solve the problem in second istance but for test i prefer use a virtual machine make with VirtualBox.

As I said in my original note:

...

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. This second and different config file had different listen ports and a different base_dir. So what Gabriele Fergola and

Odhiambo Washington suggest has already been done.....

Did you override login_dir instead of leaving it as default under base_dir? If so, you'll need to change that too. Your errors look exactly like what happens if login_dirs are the same.
