Syntax error in a resource usage counter renders the system inoperable

Question

Syntax error in a resource usage counter renders the system inoperable

Closed this issue 4 months ago · 0 comments

Expected Behavior

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.

Additional Context

Observed as of rev. 757f781
