dovecot - Jul 2019 - Orphaned processes after doveadm log reopen

I rotate logs every night on my Director, running "doveadm log reopen"

I've noticed a problem with processes not closing correctly, they can be 
open for days and cause corrupt index files because they are connected 
to different backends (so it writes to the wrong server when the process 
disconnects)

23518 ?        S    140:53 dovecot/anvil [4 connections]
23519 ?        S    444:45 dovecot/log
23520 ?        S    497:19 dovecot/imap-login [8 pre-login + 27 proxies]
23531 ?        S      0:27 dovecot/config
26201 ?        S    551:53 dovecot/imap-login [7 pre-login + 33 proxies]
22126 ?        S    960:15 dovecot/pop3-login [28 pre-login + 396 
proxies]
59515 ?        S    218:32 dovecot/pop3-login [44 pre-login + 468 
proxies]

Is there any way to force these orphaned processes to terminate after a 
certain time?

I ran "strace -f -p" on 59515 which caused the process to wake up and 
terminate? Very strange.

I can send the dump from strace if you want, but since it contains 
addresses I would prefer it to be done off-list

It happens on "/etc/init.d/dovecot restart", not "doveadm log
reopen" -
sorry

So it happens when you run killproc on dovecot

Do you happen to have shutdown_clients=no ?
