Error after upgrade test

[Rosenbaum, Larry M.]

We are testing the migration of Cyrus-IMAP from v2.3.15 on Solaris 9 to v2.4.12 on RHEL6.  After copying the data over to the new server and starting cyrus-imapd, I see the following errors in the log file:

Jan 20 11:51:33 email-new master[7835]: setrlimit: Unable to set file descriptors limit to -1: Operation not permitted
Jan 20 11:51:33 email-new master[7835]: retrying with 1024 (current max)

Jan 20 11:51:33 email-new master[7835]: ready for work

I am concerned about the "Unable to set file descriptors limit" and "unable to setsocketopt(IP_TOS)" error.  What do they mean, and are they important?

Thanks,
