irule to delete the stale connections.

Hi All, I'm looking for a irule that can check the status of connections on the VIP and remove any stale connections. The reason I want this is that, I'm told there is a bug in F5 LTM versions 11....

Please find the custom tcp profile I have used. 

ltm profile tcp meshsrc_git_test {
    app-service none
    defaults-from tcp
    ecn enabled
    max-retrans 12
    slow-start disabled
}

I have tried by enabling few features on the profile, but that didn't help. I have even used the i-app to create a VIP for this which added the customized Protocol profiles (Client & Server) whose configurations were default WAN/ LAN tcp optimised settings were enabled. 

  meshsrc_git_test_tcp-lan-optimized
        app-service meshsrc_test
        defaults-from tcp-lan-optimized
        init-cwnd 16
        init-rwnd 16
        slow-start enabled

meshsrc_test_tcp-wan-optimized {
    app-service meshsrc_test
    defaults-from tcp
    nagle enabled
    proxy-buffer-high 131072
    proxy-buffer-low 131072
    receive-window-size 65535
    selective-acks enabled
    send-buffer-size 65535

Please let me know if I have to make any specific changes.

thanks.
