Hi Chris,

What platform (operating system version, Java version, QFJ
version. etc.) are you using?

That's good to hear.

It appears the QFJ files can be used by the JNI code but not
the other way around (Unicode issues). If it's important=20
to be able to change libraries during a trading session we could
make the files compatible but it's not currently a high priority.

I just ran the order executor (Windows XP Pro, Java 1.4.2_07,
QFJ CVS head) and it had no problem connecting to port 443=20
(after I disabled IIS).

Again, please give me the information on the platform you are using.
Can you tell me more about the test you are doing? Is the acceptor=20
sending a constant stream of messages (< 10 second) interval? Is the
application (initiator) also responding at a rapid rate? I'm asking
because there wouldn't be any heartbeats in that scenario.

I've run tests with the CVS head where I sent 1,000,000 messages
from an initiator to an acceptor without any heartbeat problems.
However, it's possible the problem is in the other direction.

Steve
