amazon-ecs-agent: seeing a number of `Error serving to ACS Webserver: EOF` events trickle in once upgraded to v1.29.0

Summary

seeing a number of Error serving to ACS Webserver: EOF events trickle in once we upgraded to v1.29.0

Description

seeing a number of Error serving to ACS Webserver: EOF events trickle in once we upgraded to ecs-agent v1.29.0

re-connects seem to happen just fine so maybe this could be an INFO ecs-agent reconnection log rather then an ERROR?

Expected Behavior

no errors logged 😄

Observed Behavior

events like this in the ecs-agent log

FYI, the missing metrics issue is already resolved and customers using 1.29.0 should be seeing the expected metrics in CloudWatch.
