I have been running with Jconnect for a few months, and I noticed that
the http gateway uses 100% of my NT Server 4.0 processor
(service pack 3). I then adjusted the priority of the http gateway
to 'low' to keep the http gateway from taking processing power away
from the other applications running on the NT Server. The http gateway
still takes 100% CPU, but it does not degrade the server due to
its low priority. It seems to take about three hours or so before
the http gateway spikes to 100% and stays at 100%.

Here's the interesting thing, I have no degradation of performance from
the applets prospective, but the http gateway process seems to
stay at 100% (very strange). The NT task manager reports the processing
as using about 4Meg of memory (not a lot) and that number does not
seem to grow.

Has anyone had this type of experience with the http gateway? I have
been using jConnect 2.0 and I tried it with jConnect 2.2.

Thanks!

That problem in the Cascade gateway was fixed quite a while ago,
unless you are finding something new here. Are you sure that
you downloaded the latest version, and the class files that get
loaded when you start your gateway are from the latest version?
