    196196Startstop_solaris: There MAY be a problem with the signal that startstop sends to modules during the shutdown sequence. The shutdown sequence is started (after typing "quit" to startstop or running "pau") by startstop placing a terminate message on all transport rings. Modules should see this message and start  
    197197their own shutdown. After a configurable delay, startstop checks to see that all modules have exitted. Any that are still running are sent a signal to terminate them. Currently that signal is SIG_TERM. But since wave_serverV has a handler for SIG_TERM, wave_serverV sees that as essentially the same as a terminate message.  
    198 So if wave_serverV is having problems completing its shutdown, SIG_TERM won't do anything. The result is that startstop may give up and exit, leaving wave_serverV running. If that happens, the operator will have to terminate wave_serverV by doing "kill -9 <wave_serverV-pid>". That may leave shared memory and semaphores stranded in the kernel: run the command "ipcs -a" to see. If necessary, the stranded shared memory and semaphores may be cleaned up with the ipcrc command; must be run as root; see the man page. This problem only exists on Solaris/Unix, not on WindowsNT.
