Would we need 4.3 clone for this ticket (GA?) ? I don't see it's different there as far is it goes for popping items from lvm cache dict outside of locks. (In reply to Amit Bawer from comment #1) > Would we need 4.3 clone for this ticket (GA?) ? > I don't see it's different there as far is it goes for popping items from > lvm cache dict outside of locks. Same issue exists in 4.3 of course. We can clone the bug and if we get acks we can backport the fixes. Fixes should be part of build 4.40.23 when available we want to add more fixes under this ticket, so moving back to NEW Can it go back to MODIFIED now? While the system was upgrade to 4.4.2
