I just saw it (~1500 users affected, dovecot disappeared)

dovecot: master: Panic: kevent() failed: Invalid argument

FreeBSD 11-RELEASE-p10, dovecot 2.2.29 (.1_2 package revision)

This thread was the only exact match on search engines…

No other match in last 60 days's logs of our two dovecot 'backends' (nor
in last 10 years from my head)

Not sure if this can help… a least for stats …

@Timo: kudos for ~15 years of not experiencing this kind of bugs :)
