Hi there!
I compiled dovecot from git on 5.2.2018.
The id of the last commit is:
$ git log --format="%H" -n 1
83b1300b96e753206f9226e3738a7ad9f5428a75
From https://github.com/dovecot/core.git
There is a new error, when i try to open a virtual folder for my archiv
(almost 30.000 mails) in thunderbird, also in k9-mail on android.

increasing the ulimit avoid this problems:
