Hi there, Could you tell us which version of Restlet edition for JavaEE you are using?
Also, how long your HTTP requests are supposed to be lasting? Best regards, Jerome -- http://www.restlet.org http://twitter.com/#!/jlouvel -----Message d'origine----- De : python [mailto:[email protected]] Envoyé : mercredi 14 septembre 2011 17:46 À : [email protected] Objet : Intermittent Problem of HTTP Connection Hanging I have deployed a Liferay Portlet which uses GWT and REST. I have this problem of thread hanging and get a Internal connect Error.. Some times it works but most of the time i run into this issue.. I am using the latest version of Restlet. Below is the Thread Dump . Any suggestions on how to fix this ? http-8080-1" daemon prio=6 tid=0x066e9c00 nid=0x1fe4 waiting on condition [0x08 38d000] java.lang.Thread.State: TIMED_WAITING (parking) at
