Just to let you know that the current version upstream is not enough
to solve the problem. I copied their version in the jessie release,
backported it to wheezy and tried it.
After less than 24h, the system is stuck again, The problem can be traced to:
@wrap_exceptions
def threads(self):
Where there is still an open that does not close properly:
