3628426 - A task is waiting forever to get a buffer latch held by a non-existent process - SAP ASE

A process was in "latch sleep" status since was waiting to get a buffer latch. Tried to kill it, but it could not be killed:

======

Killing spid: XXXX will not be immediate because it is waiting for a latch held by spid: YYYY.

======

Process that was holding the latch didn't exist. It was a phantom process. There are not errors related to this process on ASE's log.
