Przemek Bruski commented on AMQ-5249:
-------------------------------------

OK, we'll upgrade as soon as it's available. It will take some time before it ends up \
on production and then we should wait for at least two weeks before confirming the \
fix - the rate of occurrence is roughly once per week.
