Hello,
it seems we need a dovecot developers opinion. May be we hit a bug or cant help ourselves.
Thanks for your answer. Core dump with backtrace would help, if possible to acquire. Please refer to https://dovecot.org/bugreport.html for information how to get a core dump.

Unfortunately its hard to get a backtrace because dovecot is not crashing. so it seems to be more a kind of logic problem in code and no unexpected situation. yesterday evening i had next incident. I upgraded from 2.2.33.2 to 2.2.36.1, but same behaviour. Also 2.2.36.1 is tricked by the broken index and delivers no new mails. it starts delivering if i delete index files. At this point i cant tell if 2.2.36.1 also has same bug and writes a damaged index, but very likely. We dont know this problems with 2.2.22, between 2.2.22 and 2.2.33.2 a change on mbox-index code must happend which leads to this big problem. So imapd cant do what he was created for.
For next incident i prepared a 2.3.2.1 on base of Ubuntu 18.10 and will try this. In my opinion this is a major problem and i expect a lot of affected people with version > 2.2.22 and classic mbox-storage.
Thanks, Hajo
