It's 25.  I know what the options does.  What I want to know is what's
involved.  If I raise it to 50, will it eat up memory or communications
buffers?  Is that inducing a potential crash situation instead of the
bottleneck I have now?  I've found nothing documented about what a
"session" really is, and it's frustrating.  In the mainframe environment I
came from, there were all sorts of formulae that I could use to calculate
the effect of adding more "users" or "threads" or whatever.  Buffer space
for a system option had to balanced against the needs of other functions.
but there was usually a source to turn to when using such options.  In
ADSM, there is very little except the collective experiences of this listl
Hence the question.
