JNSimba opened a new pull request, #539:

# Proposed changes
Issue Number: close #xxx
## Problem Summary:
When the http thread fails, the main thread will not be able to perceive the
exception, which may cause write blocking. In this case, you can reduce the
`sink.check-interval` time.
This pr is used to optimize the situation when the check-interval is closed
(or the time is relatively large)
