When the current value in a resource usage counter file set to 0, the system should understand it
An error in a resource usage counter must not impact the rest of the system operation
Actual Behavior
A failure to parse Duration out of a value in the resource usage counter (literally, 0) renders the system unusable at startup
Root Cause
Exception traces below.
