Hi,

I developed a network extension program on macOS. I tried to update the program by changing the version number. My update process was to first turn off network filtering via "NEFilterManager.sharedManager.enabled = NO", and then use "[OSSystemExtensionRequest activationRequestForExtension:bundleid queue:dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0)];" to let the system replace the old network extension program.

However, sometimes the old network extension process will become a zombie process like pid=86621 in the figure. As long as the zombie process exists, the network cannot be used. After about 10 minutes, it will be cleared and the network will be available. Restarting Wi-Fi can also clear the zombie process immediately. Why is this? How to avoid this problem?

Are you using zombie in the technical sense used by Unix-y systems? That is, ps ajx shows Z in the STAT column?

Or are you just referring to a process that hangs around longer than you expect it to?
