Hi Santosh

We've had similar issues with server jobs servicing ODBC requests etc,
that seem to go awry and just chew up storage, even after the  user has
shut off their PC. We got the space back once the offending job was
ended. To identify them I wrote a small routine we can run on an ad-hoc
basis when storage seems to be taking more of a hit than usual. The code
is available at http://www.dbg400.net/extras.html#chktmpstg - it's just
a single RPGLE routine.

What it doesn't report is large files generated in QTEMP (by query, SQL
etc) that I haven't found a way of identifying yet.

Another thing to look at might be abnormal numbers or excessive size of
spool files. Just prior to a V5R1 upgrade on one of our machines a
Domino job started spitting out 2000+ page error reports at the rate of
1 or two a minute. Over the day (before we spotted it) it had taken
around 10% of the DASD.
