SOLVED: Re: Dovecot does not start on MacOS 12.01, and now 13.2.1 - RLIMIT_DATA

[James Brown]

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

https://www.mail-archive.com/dovecot@dovecot.org/msg84776.html


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.
