  • Killing spid with process in latch sleep gives the following error:

    Attempted to kill spid 230 on entity <Server>
    Killing spid: 230 will not be immediate because it is waiting for a latch held by spid: 3272.

  • The spid causing blocking (3272) is in latch sleep and is also not killable because it is also waiting for a latch.
