We are running RFAJ 7.6.0.E9 through 22.214.171.124 on various Linux systems that connect to various ADS 2.5.0.L1 also running on Linux. The ADS disconnects the session due to not receiving 3 consecutive heartbeats from the RFAJ systgems. This has been confirmed by watching the communication between the RFAJ systems and the ADS's. The JVM, and the relevant code, has been verified to be running before and after the ADS initiates the disconnect. Has anyone seen this behavior? Does anyone have any suggestions for where to look on the RFAJ system to determine where, or why the heartbeats are not being sent?
