-----Original Message----- From: Babak Vahdat [mailto:babak.vah...@swissonline.ch] Sent: terça-feira, 20 de agosto de 2013 15:32 To: users@camel.apache.org Subject: RE: Load test on camel-netty If Oracle/Sun JDK is in use then maybe ask for a heap dump as the OutOfMemoryError happens: http://docs.oracle.com/cd/E15289_01/doc.40/e15062/optionxx.htm#BABBBEAJ Then you could analyze the dump (e.g. using http://www.eclipse.org/mat/) to see where that huge memory consumption or the leak (if any) comes from.
