Description

I have two HTTPs monitors for the same site, exactly the same parameters except one is checking every 30 seconds, and the other every minute.

This just happened for the 1 minute site:

The 30 second site is all good:

It also happens the other way (i.e., 30s gets bogged down whereas 1m shows no faults).

👟 Reproduction steps

Add two sites, dockerized, one with 1m and one with 30s.

👀 Expected behavior

This shouldn't happen.

😓 Actual Behavior

Occassional bogged down monitors

Tested a bit but cannot reproduce. I suspect it has something to do with how the DNS gets limited queries, which #1598 should fix.

I have three separate sites with this issue (all have 30s and 1m monitors). One site uses Cloudflare DNS and other two Gandi.

The console print in docker isn't that useful, probably.

I've double checked by also adding a monitor of IP address and it has the same problem, so it's not DNS related.

Seems to be fixed by latest Windows update, so closing.
