One step further in my quest to create a replacement mail server.
I now have my old mail server (2.3.19.1, macOS + MacPorts) and my new (2.3.20, Alpine Linux, Docker, apk package). When I turn on replication it works, but, after a while I see:
Jan 06 00:50:31 replicator: Panic: data stack: Out of memory when allocating 268435496 bytes Jan 06 00:50:32 replicator: Fatal: master: service(replicator): child 133 killed with signal 6 (core dumped) Jan 06 00:50:32 lmtp(pid 195 user sysbh): Warning: replication(sysbh): Sync failure: Jan 06 00:50:32 lmtp(pid 195 user sysbh): Warning: replication(sysbh): Remote sent invalid input: -
I've removed synchronous operation for now (found a message on the net suggesting that) but is this known and what does it mean?

Dovecot default memory limit is 256M. You should probably set
service replicator { vsz_limit = 2G }
because replicator might have to use more memory, especially for larger indexes.

That is a good tip as well.
I had followed this bit of experience from someone else: https://marc.info/?l=dovecot&m=164438199727640 https://marc.info/?l=dovecot&m=164438199727640, haven't seen any err message since. But that might be because they are in sync now and both sides are aware. Can I trigger full replication again so I can test?
