StatsdMeterRegistry stops sending measurements

See original GitHub issue

Hi,

it seems that https://github.com/micrometer-metrics/micrometer/issues/2138 didn’t fix the underlying issue.

seems that there’s a bug there that causes FD to be opened and never closed. here are some stack traces

After a lot of investigation and debugging with the help of @violetagg, I think we understand what is happening and have an idea for a fix, which we will need some people experiencing this to test out with snapshots once available. I have no way of reliably triggering this issue, despite much effort. To state what we think we know about the issue:

  • micrometer-registry-statsd with UDP from version 1.5.2 can be affected
  • It is triggered by an exception (other than PortUnreachableException) in sending StatsD metrics
  • Logic to reconnect has a bug that results in an infinite loop of opening and closing connections

An exception other than PortUnreachableException when sending StatsD metrics is the part I do not know how to reliably reproduce. All micrometer-registry-statsd users may not experience it either. For those that do experience it, it is a severe issue and it is high priority for us to get a fix out for this.

@garry-mcfly thank you so much for trying out snapshots and reporting back. This is very helpful. We’ll work on getting another patch release out soon with the fix unless someone else reports a problem before then.
