Idle session causing LB session to move on another server in the LB pool

Hi, We have an application accessed through LB VIP. VIP has two pool members, both are active. We are using an iRule to do session persistence on ASP.net_sessionID. Details of the VIP are listed be...
application delivery
devops
iRules

We have observed that if session is idle for more than 3 minutes, it gets disconnected /transferred to another server in the pool.

universal persistence timeout is 180 seconds by default.

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm persistence universal
ltm persistence universal universal {
    app-service none
    mirror disabled
    rule none
    timeout 180
}

Thank You nitass for your quick suggestion. We will try to create a customized persistence profile (which calls ASP.NET_Sessionid iRule) with increased timeout and assign it to the VIP and give a try to check the session. Thanks, Rajendra
