1. If you want to be absolutely sure, look for your real-time thread(s) in
this output:

/usr/bin/ps -eLc | grep RT

Other Ideas:

2. Maybe a little late for this, but consider using TNF to instrument your
real program to help isolate the segment that is causing the unexpected
delay. See http://developers.sun.com/solaris/articles/tnf.html.

3. The system interface guide, real-time section says you should lock your
program in memory and also pre-load libraries. This may be a long shot.
