Jython leaking file descriptors. Sockets ends up in CLOSE_WAIT and then never gets garbage collected. To reproduce: If you run the jython CLI in one shell and then look at the socket states in another, you can see that they ends up in CLOSE_WAIT forever. The same problem occurs when using org.python.util.PythonInterpreter. $ java -cp jython-standalone-2.5.3.jar org.python.util.jython >>> import urllib2 >>> urllib2.urlopen('http://www.google.com/notfound') >>> urllib2.urlopen('http://www.google.com/notfound') >>> urllib2.urlopen('http://www.google.com/notfound') >>> urllib2.urlopen('http://www.google.com/notfound') >>> urllib2.urlopen('http://www.google.com/notfound') To check sockets: $ netstat -ant\|grep CLOSE
