Hello,

I have a character device that holds a mach-style semaphore. Most of the time it is down so my user side program reading from it will block. I have an interesting problem in that when I plug and unplug my ethernet cable my semaphores get released with a code 37. Any advise on why the mach kernel would be releasing my semaphores on such an event?

Thanks,
Eric
