Telemetry can only create 10 conns by default, each of which is processed
by a thread.
When a thread fails to write using socket, the thread will end directly
without reducing the total number of conns.
This will result in the machine running for a long time, and if there are
10 failures, the telemetry will be unavailable
Fixes: 6dd571fd07c3 ("telemetry: introduce new functionality")
