critical impact:

SA_CLDNOTIFY - not available (CrUn109)

Problem description

The SA_CLDNOTIFY flag for the sigaction function exists on Tru64 UNIX but not on HP-UX.

When the SA_CLDNOTIFY and SA_SIGINFO flags are both set, two SIGCHLD signals are queued to the parent for each abnormal termination of a child process that includes a core dump: an early notification signal and a final notification signal. The early signal tells the parent process that it can start a failover operation or take other appropriate action. The final signal tells the parent process that the child process is now a zombie and can be cleaned up with a call to wait.
