Hi, I'm making an application that make an AJAX request frequently from page to page in xwiki. About 1 per 10s The request look like this: $.ajax({ type: "GET", crossDomain: true, url: "/xwiki/bin/get/Lib/LibPage?outputSyntax=plain", dataType: 'text', data: data2send, success: function(result) {...}, error: function(xhr, status, error) { console.log(error) console.log(status) console.log(xhr) } }); And respone is simple as a text or something like a JSON Map, List. I took a look at jconsole and here it is <http://xwiki.475771.n2.nabble.com/file/n7587262/9-26-2013_1-51-09_PM.jpg> Please help! I don't understand how xwiki works on this. Thank in advanced. -- View this message in context: http://xwiki.475771.n2.nabble.com/Frrequently-AJAX-request-caused-PernGen-Ex... Sent from the XWiki- Dev mailing list archive at Nabble.com.
