The key problem seen is that ose.servgrpibmoselink1 returns null for several properties - ose.sessionid.length, affinityidname, ose.failure.retry_timer, and ose.connection.inetretries. The request for /fmc/XmlTestServlet host from fmcprod07:80 thru default_host returns a null. Session affinity is however enabled.
