Incoming L2TP sessions stuck in wt-con on Cisco-7,200?

    Hello,
    We are using Cisco 7,200-G1 as an LNS for our local carrier ADSL service
    termination (the carrier is using Redback for its LAC). We have about 30
    tunnels to 30 different Redbacks.

    After there is a communucation disruption and all users reconnect I have
    problem with one Redback. There are a lot of sessions stuck in wt-con state and
    more users cannot connect to this tunnel only. From a TCPDUMP I see that the
    Cisco's LNS delays its response (ICRP) to the session initiation request (ICRQ)
    on this tunnel, thus sessions gets hung. I suspect there is some misbehaving
    client which tries to generate a lot of connections (hard to debug with such
    large amount of data).

    Anyone had such a problem and has some clew how to solve or at least
    workaround this problem?

    Thanks! __Yehavi:
