Hello Jeanfrancois,
yes we are on Linux. Attached you can find data you have required.
Today we tried with beta java jdk 1.6u18, results in file are from today.
http://www.nabble.com/file/p25716494/jstack.txt jstack.txt
Attached you can also find 2 images.
One is printscreen of jConsole, where you can see CPU usage. Here you can
see CPU usage growing, but when we started jVisualVM, CPU usage has fallen.
Again when we closed jVisualVM, it grew back on.

On second image ou can see CPU usage of threads.

Do you have any idea what are we doing wrong?
Thanks for your help.
