I have a pair of 11503's configured in one arm mode runnig version 08.10.1.06. Everything works well, but some clients connect to Oracle databases and run queries that last for 5 - 6 hours. The session is OK for 3-4 hours then the CSS issues a RST and kills the connection. The same config (not in one arm mode) on a 11150 with version 6.10 works fine and doesn't issue a RST. Any ideas ?
