    Webservice won't scale: Blocked Threads - XPathExpressionImpl

    a39eb310-d6e3-4fd2-b812-7d202b026858

      Hi,

       

      I am load testing a SOAP webservice deployed on Weblogic Server. It is giving very poor throughput and on investigation of thread dumps (see link below), I see blocked threads. See https://drive.google.com/file/d/0BwRchYLsDMZia3lfbkRHZ1YwOVk/edit?usp=sharing

      Search for "XPathExpressionImpl"

       

      Server specs are:

      Versions:

      WebLogic Server Version: 10.3.3.0


      JVM args:

      weblogic 17118 17034 12 04:55 ?        00:06:19 /apps/sw/oracle/mw/jrockit-x64/bin/java -jrockit -Xms6g -Xmx6g -Dweblogic.Name=HWP-NGI-1 -Djava.security.policy=/apps/sw/oracle/mw/app_11.1.1.3/wlserver_10.3/server/lib/weblogic.policy -Dweblogic.ProductionModeEnabled=true -Xmanagement:ssl=false,authenticate=false,port=7099 -Dweblogic.nodemanager.ServiceEnabled=true -Dweblogic.security.SSL.ignoreHostnameVerification=true -Dweblogic.ReverseDNSAllowed=false -Dweblogic.Stdout=/logs/servers/HWP-NGI-1/HWP-NGI-1.out -Djava.util.logging.config.file=gs_logging.properties -da -Dplatform.home=/apps/sw/oracle/mw/app_11.1.1.3/wlserver_10.3 -Dwls.home=/apps/sw/oracle/mw/app_11.1.1.3/wlserver_10.3/server -Dweblogic.home=/apps/sw/oracle/mw/app_11.1.1.3/wlserver_10.3/server -Ddomain.home=/apps/services/mw/HIAS-WLS-PAT -Dcommon.components.home=/apps/sw/oracle/mw/app_11.1.1.3/oracle_common -Djrf.version=11.1.1 -Djrockit.optfile=/apps/sw/oracle/mw/app_11.1.1.3/oracle_common/modules/oracle.jrf_11.1.1/jrocket_optfile.txt
