It may well be that the log isn't 'supposed" to grow but that isn't what
I experienced. I ended up halting TSM and restarting as I did not want
to take a chance that it would fill completely even though I do have
headroom to extend the log further.

The administrator of the server tells me he stopped all TSM services
that were running but that didn't seem to cancel the sessions either,
and I thought it would. If it was supposed to then I'd have to question
the system he was on.
