Hi!

That solution is bit overly broad way to solve this, I would instead recommend

service log { vsz_limit = 0 }

so that only service log is affected.

Ok... so for some reason the default_vsz_limit is too low for MacOS.

Can you try

default_vsz_limit = 2G?

We don't recommend setting it to 0.

2G fails.

This must be some change in MacOS 12 (Monterey). I have been running Dovecot for 10 years on MacOS with the same config, and only after upgrading to 12.0 did this issue surface.

I think this is happening because MacOS no longer supports RLIMIT_DATA. We'll try to look into this. default_vsz_limit = 0 seems good enough workaround.

I think this is happening because MacOS no longer supports RLIMIT_DATA.

I just tried on macOS 12.1 beta and getrlimit(RLIMIT_DATA) gives RLIM_INFINITY for both current and max (and so does my macOS 10.14 box).

On Monterey, using setrlimit() to reduce 'current' works for large numbers, but does return error for low numbers. On my hardware at least, it starts to return error around 419 GB.
