NIS lookups fails for getpwuid in presense of repeated signal event
Issue
- A program doing a kind of profiling of itself using alarm()/SIGALRM each second, gets stuck in getpwuid() and similar calls trying to get UID which is in NIS.
- Whenever there is an UDP packet loss, ALRM signal arrives while the getpwuid() call is waiting in poll() for a reply from NIS and getpwuid never returns.
Environment
- Red Hat Enterprise Linux 5
- NIS
