please appreciate that i am trying to help ....
after much testing i can now reporduce the replication issues at hand
I am running on freebsd 12 & 13 stable (both test and production servers)
sdram drives etc ...
Basically replication works fine until reaching a folder quantity of ~
256 or more
to reproduce using doveadm i created folders like
INBOX/folder-0
INBOX/folder-1
INBOX/folder-2
INBOX/folder-3
and so forth ......
I created 200 folders and they replicated ok on both servers
I created another 200 (400 total) and the replicator got stuck and would
not update the mbox on the alternate server anymore and is still
updating 4 days later ?
basically replicator goes so far and either hangs or more likely bails
on an error that is not reported to the debug reporting ?
however dsync will sync the two servers but only when run manually (ie
all the folders will sync)
I have two test servers avaliable if you need any kind of access - again
here to help.

i have been going through the c code and it seems the replication gets
requested ok
replicator.db does get updated ok with the replicated request for the
mbox in question.
however i am still looking for the actual replicator function in the
lib's that do the actual replication requests
the number of folders & subfolders is defanately the issue - not the
mbox pyhsical size as thought origionally.
if someone can point me in the right direction, it seems either the
replicator is not picking up on the number of folders to replicat
properly or it has a hard set limit like 256 / 512 / 65535 etc and stops
the replication request thereafter.
I am mainly a machine code programmer from the 80's and have
concentrated on python as of late, 'c' i am starting to go through just
to give you a background on my talents.
It took 2 months to finger this out.
this issue also seems to be indirectly causing the duplicate messages
supression not to work as well.
python programming to reproduce issue (loops are for last run started @
200 - fyi) :
# cat mbox.gen
#!/usr/local/bin/python2
import os,sys
from lib import *
user = 'paul(a)paulkudla.net'
"""
for count in range (0,600) :
box = 'INBOX/folder-%s' %count
print count
command = '/usr/local/bin/doveadm mailbox create -s -u %s %s'
%(user,box)
print command
a = commands.getoutput(command)
print a
"""
for count in range (0,600) :
box = 'INBOX/folder-0/sub-%' %count
print count

#sys.exit()
