      When running tests for RFE EAP7-867, the client is logging sampling errors due to
      java.net.SocketTimeoutExceptions:

      We have also tried to set bias-lifespan="0", but that did not help.
      There are two types of tests:

      1. failover tests
      Sampling errors occur after failover.

      run with bias-lifespan="0":
      overview: 1714 sampling errors
      http://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-scattered-sync/17/artifact/report/failover.txt
      client log:
      http://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-scattered-sync/17/console-perf17

      run where bias-lifespan is not set:
      overview: 620 sampling errors
      http://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-scattered-sync/16/artifact/report/failover.txt
      client log:
      http://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/perflab_eap-7x-failover-http-session-shutdown-scattered-sync/16/console-perf17/

      2. stress tests
      Sampling errors occur regularly, in larger numbers starting from 6th iteration till the end of the test.
      run with bias-lifespan="0":
      http://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/eap-7x-stress-session-scattered-sync/15/
      run where bias-lifespan is not set:
      http://jenkins.hosts.mwqe.eng.bos.redhat.com/hudson/job/eap-7x-stress-session-scattered-sync/13/

      Also, WFLY-10273 is occurring in these runs.
