Re: Multiple zombies after using smbfs.ko

:Sorry, I've made some errors in previous messages.
:In latest code zombies occured *after* i tried to unmount the smbfs and before i unloaded
:the module. If i do not unload the module nothing happens, just zombies.
:With code that was before commit at 6 Jan 2005 there is a system crash after 
:`kldunload smbfs; ps aux`.
:Sergey Gluschenko

    Well, I would expect the system to crash if you tried to kldunload
    smbfs.  Don't do that!

    The zombie issue is the one we really need to figure out.  Are you
    shutting down any programs using the share before unmounting it or
    are the zombies basically the programs that were trying to use the
    share at the time you unmounted it?  umount shouldn't allow that,
    unless you are doing a forced unmount.

    What I think I would like is a kernel crash dump showing the system
    in this state where there are zombie processes created due to this 
    issue, so I can figure out what they are stuck on.
