Panic -Dsync Replication

[Antonino Sidoti]

Hi,

I am seeing this;

Jun 07 16:17:22 Warning: lmtp(nino at sidoti.id.au)<20211><vJkREfC5vWDzTgAAv/fbcw>: replication(nino at 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.
