BugId 4620185

Problem Summary: If the rpc.pmfd daemon monitors a process that forks a new process as the result of handling a signal, then using pmfadm -k tag signal might result in an infinite loop. This might occur because pmfadm(1M) attempts to kill all processes in the tag's process tree while the newly forked processes are being added to the tree (each one being added as a result of killing a previous one).

This bug should not occur with pmfadm -s tag signal.

Workaround: Use pmfadm -s tag signal instead of pmfadm -k. The -s option to pmfadm does not suffer from the same race condition as the -k option.
