Ok running :
freebsd-12.1 dovecot-2.3.18.current dovecot-2.3-pigeonhole-0.5.18.current
simply put replication works fine on smaller email boxes without issues.
dsync also works when run manually, longest sync is 60 secords or so when using dsync so need replicator bumped up ?
i get the fact that the file locking issue relative since a larger mailbox will take longer to replicate when an email comes in ?

so what i need is where fcntl is setting a 30 second timeout for replication (i have adjust all the others in the src code)
simply put replicator fails and retries and keeps failing which is understandable as it probably needs a little more time ?
