      Description


      On Solaris Sparc, in C2 mode ( c2 & 64 bits), volanomark and volanotest failed
      intermittenly with the message:
      java.net.SocketException: null fd object

      Frequency:
      VolanoMark VolanoTest
      -server 0.2% 6%
      -d64 0.03% 9%

      The failures happen more frequently with VTEST.
      The error did not occur on Solaris x86.

      How to reproduce the failure:
      There are two alternatives to reproduce the bug, to use bigapps test scripts
      or to use commandline.

      To use bigapps test scripts to reproduce the bug:
      1. telnet to a Solaris Sparc machine
      2. export JAVA_HOME=<your java home>
      3. To run volanotest,
      /net/jtgb4u4c.sfbay/export/sail8/bigapps/tests/runvtest.ksh -server (or -d64)
      To run volanomark,
      /net/jtgb4u4c.sfbay/export/sail8/bigapps/tests/runvmark.ksh -server ( or -d64)


      Alternatively, you can reproduce the bug from commandline:
      1. cp -r /net/mooncake.sfbay/export/bigapps/bigapps_commandline/vtest <some dir>
      2. cd <some dir>
      3. export JAVA_HOME=<your java home>
      4. start the server by executing the command
      export VOLROOT=/net/jtgb4u4c/export/sail8/bigapps/ws/master/dist/volano/vmark2.1
      .2

      ${JAVA} ${JAVA_ARGS} -mx64m -Xverify:none -cp ${VOLROOT} COM.volano.Main `pwd`/testprops.txt &

      where $JAVA_ARGS is either "-server" or "-d64"
      5. run the client in a loop
      export VOLROOT=/net/jtgb4u4c/export/sail8/bigapps/ws/master/dist/volano/vmark2.1
      .2
         while true; do
            ${JAVA_HOME}/bin/java ${JAVA_ARGS} -mx128m -Xverify:none -Dinstall.root=${VOLROOT} -cp ${VOLROOT} COM.volano.Test -run -port 8500 -file vtest2_1_2.log
         done

      where $JAVA_ARGS is either "-server" or "-d64"
