One thing I would like to mention is that when I do a priocntl -l, it shows only the SYSTEM, INTERACTIVE, and the TIMESHARE classes. REALTIME does not appear in that list. But when I issue the command *priocntl -e -c RT -p 59 "path to the executable"*, then priocntl does not complain. Infact, I see that process running with priority 159, and nice value -20. Looks fine to me, but it doesn't seem that the application does any better in terms of emptying the socket buffer! Is it running in the real-time mode?
