      Description

      Platform: T5200
      OS: s10u5 + 137137-09

      test matrix:

      5u19: after 23M ops -> no error
      6u14: after 5.6M ops -> java OOM

      With 6u14, after 5.5 Millions socket connection
      operations, the process size approached the 32bit process size
      limit of 4G, and C heap usage is 3.9G. There is native memory leak
      with 6u14, which causes the OOM.


      Using libumem, I took samples of test run at around 37 thousands and
      then at 110 thousands socket connection operations mark with 6u14 and 5u19.

      Here are the findings:

      C heap usage:

      #ops 6u14 5u19
      ----------------------
      37000: 106MB 33MB
      110000: 217MB 33MB

      libumem findleaks with 6u14: shows insignificant leak buffers

      The testcase is in the form of a jython script, which continuously open SSL
      connections to a webserver.

      Here's the jython code:

      i = 0
      e = 0
      while 1 :

        try :
          i += 1 ;
          sslsf = SSLSocketFactory.getDefault() ; ssls =
          sslsf.createSocket(str(sys.argv[1]),int(sys.argv[2])) ; ssls =
          ssls.session ; pcca = ssls.peerCertificateChain ; pcc = pcca[0] ;
          sdn = pcc.subjectDN ; if ( i % 1000 ) == 0 :
          print Date(),i,'sdn',sdn ;

        except Exception,java_exp :
          e += 1 ;
          exc_type, exc_value, exc_tb = sys.exc_info() print "Got Exception :
          "+str(exc_value) print "The (filename, line number, function,
          statement, value) is:"
          print str(traceback.extract_tb(exc_tb)) print 'java_exp',java_exp
          print 'java_exp',java_exp.printStackTrace()
          time.sleep(60) if e > 10000 :
          sys.exit()
