Doc Text: |
Cause: An upstream kubernetes bug resulted in the API client not recovering reasonably quickly after recovery from a tcp-reset. Since controllers/operators inherently maintain client connections to the api server, they could be impacted by this.
Consequence: Client logs could be flooded with "Timeout: Too large resource version errors" when connectivity was lost and and then regained.
Fix: The upstream kubernetes 1.18 fix was pulled into samples operator 4.5.z
Result: Samples operator is no longer susceptible to this hot loop of errror messages.
