Try manually running:

MAIL=~Maildir /usr/local/libexec/dovecot/imap
x select inbox

and check if that process also is leaking .customflags files?

And is it really the same .customflags file that is open 15 times?

Do you use INDEX=MEMORY?

Then that patch probably doesn't help. Hmm. There's another way actually
for leaks to happen but I think it also leaks .data files. Happens when
opening indexes fails because it has to be rebuilt. Shouldn't happen
normally so I'm not sure if that's your problem either. I'll fix that
later today anyway.

cd dovecot-0.99.10
patch -p0 < file.diff

(or -p1 sometimes)
