! stream command showing stream identifier XXX

Question

When I run the team! threads, in the left column for several threads I see id as XXX. I understand that this means dead threads. Does this include any threads that exited (gracefully or shamelessly), or is it for any streams that did not exit gracefully and were killed using APIs such as Abort or Interrupt.

Answer 1

You are right, threads marked as XXXX are dead threads - i.e. they no longer exist from the intended OS. The CLR stores thread information a little longer than the OS, so you see dead threads on output.

Yes, both normally completed and forcibly killed threads appear with the release of XXXX.
