Здравствуйте.

Столкнулся я с неприятным поведением dovecotю

Имеется сервер на p8, на котором работает почтовая система 
(postfix-2.11.7-alt2+dovecot-2.2.33.2-alt0.M80P.1+dovecot-pigeonhole-0.4.21-alt0.M80P.1).

В dovecot используется imap+sieve, почта доставляется в ящики 
посредством LMTP. Пользователи виртуальные из LDAP, все ящики в системе 
под одним uid (vmail/vmail). Авторизация - PLAIN/LOGIN/NTLM.

Все работает как и ожидается, за исключением того, что периодически 
(закономерности обнаружить не удалось) падают процессы dovecot 
auth-worker и хелпер ntlm_auth. Dovecot их тут же перезапускает, но все 
равно это совсем не нравится. В логах при этом следующее:

Падение auth-worker:

Про auth-worker удалось найти следующее обсуждение в списке рассылки 
dovecot: 
https://www.dovecot.org/pipermail/dovecot/2018-January/110787.html , но 
как-то ни к чему оно не привело. В багзилле debian тоже есть баг на эту 
тему - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=886028, и тоже 
какой-то непонятный. Про ntlm_auth вообще ничего внятного найти не 
удалось.

Прошу поделиться мыслями, куда можно покопать на предмет избавления от 
этих ошибок.

PS Аналогичная система на t6 с dovecot 2.1.17 и аналогичными настройками 
работала годами без каких-либо сбоев.
