I am getting a lot of these messages (on the master side of replication) : dovecot: doveadm: Error: dsync-remote(userxyz): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 81589 no longer in transaction log)
Having "Error" and "Warning" on the same line is confusing, to start with. If I get it right. it means that very often (incremental) sync fails and replication starts again after 5 min but this time by doing full sync, which, I guess, is not good (more resources used). Since I am doing only one way replication what could be the reason for those errors/warnings? Nothing is changing files on the remote side besides dsync-server. Is there anything I can do to "fix" this ?
# dovecot --version 2.2.33.2 (d6601f4ec)
