    01.Under certain conditions, the RSE keepAlive mechanism can
       fail during it's handshake such that a short read-timeout
       causes a disconnect.
    

Problem conclusion

  • 01.In order to avoid having a short read-timeout after a failed
       keepAlive handshake, the so timeout value gets reset. In
       addition, keepAlive on the server will accept a keepAlive
       request from the client as a tacit confirmation to it's own
       keepAlive request, ensuring the handshake does not fail.
