CMS collection keep working during holiday

[Y Srinivas Ramakrishna]

Could you run with the additional option +PrintReferenceGC and see if
it sheds additional light on the problem? (Please share the resulting
GC logs.)

If at all possible, you might try rev'ing down to 6.0 and seeing
if the same behaviour reproduces or not?

I understand that some or all of this may not be possible in a
production setting.
