After upgrading influxDB from 2.5 to 3.0.0 we started to have a huge amount of thread leak causing our jenkins instance to fail. We had to revert and redeploy Jenkins, and I was not able to capture a thread dump. I will update this ticket if/when I am able to have more information on the thread leak.

It happened about ~6h after startup, so for us this means after about 15,000 jobs, all with post-deploy influxDb publisher.

We used telegraf to have an influxDB listener v2, and configured the plugin to use the v2 HTTP client.
