cyrus-master errors

[Norman Zhang]

Hi,

I'm seeing the following errors in /var/log/mail/errors

Nov  7 12:03:07 mail cyrus-master[1154]: setrlimit: Unable to set file
descriptors limit to -1: Operation not permitted
Nov  7 12:03:07 mail cyrus-master[1154]: retrying with 1024 (current max)

My /etc/cyrus.conf is as follows. May I ask what am I doing wrong?

Regards,
Norman
