dovecot - May 2021 - replicator: Panic: data stack: Out of memory when allocating ...

frequently, the replicator fails on allocating memory:

replicator: Panic: data stack: Out of memory when allocating ... bytes.

I already have increased default_vsz_limit=1024M but this only increased 
the ... value.

What can be done here?

dovecot_branch=release-2.3.14
