It's the "dovecot" process that has trouble with the fd limits, because it needs one fd for each child process (for logging).
Dunno if it is related or helpful, I use v1.10 still. When I had login_max_processes_count too low, once in a while the dovecot process had lots of "socket" fd's (displayed with lsof in Linux), for which there was no counterpart in the system (lsof -U). The number of fd's did not decrease, when the number of logged in users decreased (aka over night) - I made a graph for monitoring fd's and users count. Doing a "reload" solved the problem just temporarily, we have peeks of user logins at specific parts of the year, so the problem came up every 4 or 5 days in these phases, but not in months otherwise.
