With the upgrade to 6.3, the "Client's executor exceed time limit" log line is appearing as a large percentage of log lines in all Serverless MTM logs. The units in the variables aren't useful to compare, so all the log lines look the same:

We should either suppress these log lines, or make them more useful by changing how we measure the executor time.
