[Quickfixj-users] QuickFIX/J seizes up under load

[Chris A. <chr...@be...>]

I have a FIX based system that was developed on QuickFIX/C++ with Java
bindings.  I'm interested in using QuickFIX/J for a number of reasons,
but I've had problems with it that I don't have with the native
Quickfix.

The most severe problem I have is with QuickFIX/J locking up during
heavy loads.  I have a reproducible case where the client program tries
to send nearly 500 QuoteRequest messages through a FIX router, both
running QuickFIX.  With native QuickFIX, the test runs without a hitch,
however with QuickFIX/J it will fail every time.  Anywhere between 10 to
60 messages will get through successfully but then the FIX router just
stops.

There is no indication of an error in any logs, I've been specifically
looking for any logging that may have come from
AbstractIoHandler.exceptionCaught().

Once this error has occurred, no FIX traffic will go through the
connection between the client and the router.  The socket is still open,
but the router doesn't seem to recognize it.  Eventually the client will
report the session is closed because the heart beat and TEST messages
are missing.

Without any indications of a problem in the logs, I don't know where to
begin looking for a solution.  Does anyone have an idea what could be
causing this behavior?

Thanks
Chris
