It appears especially when I launch a "complex" process when rendering
("complex" is long and UI on the server (progress bars)).
It appears when refreshing the page with the navigators'button.
I fork this complex process and it seems to work better! :-)

Yes. I did this. I can also kill the process and manually refresh the
page. But these solutions are available during developpment. When the
users, far far away with its browser, have a frozen page, he can not
open the debugger.
Currently searching for a solution...
