Maybe you could try running a shell script
that does a 'query session' every 5 minutes
and redirects the output to a log file.
That should tell you where all the sessions
come from.

Something like this should work:

--- CUT HERE ---

#!/usr/bin/ksh

while true
do
        /usr/bin/dsmadmc -id="xxx" -pass="xxx" "q ses" >> mylogfile
        sleep 300
done

---CUT HERE---
