I was just working on a pmr with a customer that was reporting similar
behavour. One of the level II people discovered that security port-scanning
software against the machine was causing this to happen. When the port was
scanned ( for example 1500, 1580) a "ghost" session was established that
could not be cancelled. After a period of a few days, the dsmserv process
would hang and stop responding to new sessions.

After configuring the port scanning software to not scan these ports, the
problem went away.

I see something similar, on both 5.1.6.2 and 5.1.6.3. Sometimes, I see HTTP
session (administrative webclient) with a question mark as platform.

Also, during a network problem, I see client sessions that last very long
(due to the network problem), and when I cancel them a sessions appears
from that client that cannot be cancelled, and remains until the server is
halted and restarted. So, I cancel a long-running backup session. That
works, then the client starts a session to report the amount of files
backup up, etc. That session never ends, and cannot be cancelled.
