Are you seeing issues with use of `scheduleAtFixedRate` which are fixed by `scheduleWithFixedDelay` ? There are nuances in the difference, which can have subtle impact. In the example you mentioned, if there is heavy gc after sending rpc request, but before task completes - fixed delay will be gc time + wait time vs just wait time. While the scenario mentioned in description is equally valid - two events getting fired very close to each other. If we are not observing issues currently, I would err on side of caution and not change behavior. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
