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()
