When enabling both comsat(biff) and imap on the machine, I found that when I restart inetd, a syslog message is generated that indicates that inetd can't reopen port 512(comsat). Looking at the output of sockstat will show same file descriptor open for all child imapd servers. >How-To-Repeat: Enable comsat and imaps Boot machine Connect to imap server run sockstat and grep for imapd and inetd.
