Sorry, replying to an old thread found on mail-archive.com http://mail-archive.com/, so it’s not threaded email.

I have just installed Dovecot onto Mac Studio running Ventura (macOS 13.2.1) and get the same error with Dovecot 2.3.20:

service(log): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument

Adding the ’service log’ stanza to 10-master.conf fixed the issue.

Is this still the correct way to handle it?

If so it would be great to have it documented somewhere. Just lucky I found the above mail thread.

Thanks,

James.

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.

A kind person who isn’t on the mailing list share the solution to this with me:

default_vsz_limit = 0

I've been happily running Dovecot on my Mac for many years (installed via Homebrew). After upgrading to Monterey (MacOS 12.01), it no longer starts:
