Barry -
I read your emails from about a month ago regarding intermittent disconnect=
s and I believe we are experiencing a similar problem.
Our app currently runs with QuickFIX 1.7.1 (socket initiator with a single =
session), patched to compile with Sun CC 5.3 with Roguewave and runs on SPA=
RC Solaris 2.8 (SunOS 5.8) w/two 1Ghz UltraSparc3 CPUs.
Below is one packet capture summary of this disconnect problem, 159.55.203.=
30 is the box running our QuickFIX app. Packet number 12 is a FIN packet wh=
ich is indicates QuickFIX closed the socket at this point. The app continue=
d to run after the disconnect and eventually reconnected.
The QuickFIX event log (see far below) simply reports 'Disconnecting' with =
no explanation reason. All incoming messages appear normal (i.e. no missing=
heart beats) until they abruptly stop, after the execution report sent in =
packet 8; only four outgoing messages (all cancels) were sent in the three =
seconds prior to the disconnect.
Is this similar to the problem you experienced? If so, how have you dealt w=
ith it?
Regards,
