With some googleing I found:
Which says its error values come from setgroups():

Which contains:

So you have 16 groups, which I believe is the default maximum.. But maybe initgroups() tries to add the gid=15 there twice and fails because of it, or something. Anyway, I don't think I can do anything about this in Dovecot.
You could of course just make Dovecot use only the default group for users, although that would require modifying the sources (eg. remove the initgroups() call completely).
