It would be much simpler for all if they just posted these things to Sun Spots, but they've got copyrights and such to protect.... I've been after our local Personal Answer Line people to explain just what error the portmapper was detecting, but for naught. Works for us -- we haven't seen any recurrences of the "YP is hosed & noone can log in!" symptom. --JH, Oracle unix systems administration Bug Id: 1025560 Release summary: 4.0.3 Fixed in releases: 4.1 Problem description: In certain circumstances, the portmapper may detect an error and exit without notification. All software which uses the portmapper will subsequently fail. Fix description: A new portmapper is available which corrects the error condition without exiting. Any other errors are now logged to /var/adm/messages. [Instructions elided for install'ing -m 755 /usr/etc/portmap.]

The portmapper problem was caused by a SIGCHLD interrupting svc_run and calling a signal handler which changed the value of errno (svc_run checks for and ignores errno == EINTR, but believes other errors are genuine and returns). The patch saves and restores errno in the SIGCHLD handler. Carl
