New installation question

[Jason Crummack]

Hi all,

I've recently installed cyrus imap 2.1.12 on to one of our servers, I
believe that i've done all the necessary configuration tasks yet when I
try and run /usr/cyrus/bin/master the following errors are seen in
syslog 

Mar 19 12:13:01 maya master[26543]: setrlimit: Unable to set file
descriptors limit to -1: Operation not permitted
