Panic -Dsync Replication

7 Jun 2021


      Hi,
I am seeing this;
Jun 07 16:17:22 Warning: lmtp(nino@sidoti.id.au)<20211><vJkREfC5vWDzTgAAv/fbcw>: replication(nino@sidoti.id.au): Sync failure: Timeout in 2 secs
Jun 07 16:17:22 Panic: replicator: data stack: Out of memory when allocating 268435496 bytes
Jun 07 16:17:22 Fatal: replicator: master: service(replicator): child 77583 killed with signal 6 (core not dumped - https://dovecot.org/bugreport.html#coredumps)
It started when I added the following to my configuration;
replication_sync_timeout = 2
If I remove the above line then sync works properly and no errors.
