Connections keep going off

Hi folks,

I have QDX 5.3 running on AIX 5.1.

Currently doing testing with a new Philips CIS system which uses Rhapsody as their interface engine. There is a firewall in between the system and Cloverleaf.

Cloverleaf has 2 OB threads configured as clients and Philips is ‘server’.

Continuously, probably after a period of inactivity, we would notice messages pending up on the Cloverleaf threads but the thread are still ‘UP’. When either side refeshes the connection independently, we would get FIN_WAIT. Normalised only after both sides stopped and started after the ‘FIN_WAIT’ was gone from netstat.

The Cloverleaf thread configuration is pretty standard throughout the engine. Could it be the firewall or is Philips missing something? Or is something amiss with the network?
