Symptoms

The issue can be reproduced at will with the following steps:

Scenario 1

1. Have 2 - DGW configured in HA mode with process names are DGW1 , DGW2.
2. Make the server parameter - enableSySessionCleanUp as 'true'

3. SLR 1 is sent to DGW1 and check we have DiameterPersistedSySessionStore cache updated as ,

["SLR_SLA_7010_Bug36266447_1", DiameterPersistedSySessionImpl{userIdentities=[0036266447]}]

4. SLR 2 is sent to DGW2 and check we have DiameterPersistedSySessionStore cache updated as ,

["SLR_SLA_7010_Bug36266447_1", DiameterPersistedSySessionImpl{userIdentities=[0036266447]}]
["SLR_SLA_7010_Bug36266447_2", DiameterPersistedSySessionImpl{userIdentities=[0036266447]}]

It is seen that enableSySessionCleanUp as 'true' and see that DiameterPersistedSySessionStore is stored with 2 session ID's as its not cleaned up.

Scenario 2

1. SLR1 established via DGW1.

2. SLR2 established via DGW2.
SLR2 was overridden the previous session (SLR1) properly.

3. STR1 comes with old session via DGW1 --Success (2001)

4. if STR1 comes with old session via DGW2 --- DIAMETER_UNKNOWN_SESSION_ID (5002)
