I'm working to finish a statistical analysis project using a large dataset and an SAS program called JMP. I'm using an old version of the program (8.0.2) which I cannot update because of expense. (I will eventually receive new stat software from my new employer, but need to finish this project first.) JMP occasionally hangs on high processor loads with rolling beachball and unresponsive windows.  I save my work a lot, and am muddling through, but there's a weird variation on the usual behavior that I haven't seen before. Once it hangs, I can kill JMP from the Terminal or Activity Monitor, but JMP's open windows stay on the screen. JMP is truly dead-- it disappears from the menubar and it's gone from Activity Monitor. It doesn't seem to spawn any daughter processes (at least none that are evident in the heirarchical view in Activity Monitor). I can restart it, but the new instance doesn't seem to recoqnize the old windows, which persist alongside new windows. They can be dragged around, but can't be minimized or closed. Mousing over them gives me the beachball. Everything else seems to behave normally. The only way to get rid of the windows, though, is to reboot, which I can do normally.

 

My question, entirely in the interest of speeding my workflow, is how do I kill these zombie windows short of reboot? I tried restarting the Finder with no effect. "sudo kill -9 windowserver" just reboots. Is there anything short of that?

 

For extra credit, one additional weird symptom is that Top (run in Terminal) doesn't display results when JMP is hung in this way. I can run it, it seems to be active, but it doesn't display any text. Activity Monitor and Menu-> Force Quit display active programs/processes correctly.

 

Any ideas?

    Logging out/in would be faster than a full reboot.

     

    Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.

     

    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

    If the problem is still there, try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.
