Locks in TSM - interpretation of output

Folks, we're at server TSM 5.1.1.4 exploiting ABC 3.1.0.4 on OVMS nodes.

Since the TSM V4 server days we experienced, at certain instances, many
sessions (up to 20 and more) from a particular node, hanging for extended
periods of time, whilst the sessions stay in RUN status, with no data flow.

Output querying the locks gives us the following details. Knowing there are
locks is one thing. Dealing with it and managing the situation is another.

It has now become a requirement that we get to the bottom of this so we can
make better decisions regarding the initiation of these sessions. They are
all generated via DCL scripts so as soon as a few sessions start hanging
additional sessions blows up the whole situation.

My question to this fraternity is:

How does one read and interpret these details shown below, and how do I tie
it up with my node, session, filespace, task numbers, etc, etc,
etc............

Your input, as always, is valued.
