Bug Report

What did you do?
I configured Service discover Azure and it worked during 1 months without problems but I got a strange error last night. See logs below.

What did you expect to see?
Should discovery VM without problems. I just restarted Prometheus to solve the problem but it appears again last night.

What did you see instead? Under which circumstances?

I'd say that your Prometheus service has hit the file descriptor limits. See https://github.com/prometheus/prometheus/wiki/FAQ#error-too-many-files-open for more details.

I'm going to close your request. If you need more help, please use the prometheus-users mailing list.
