I re-ran the failing action 3 times but it's always failing with

FAIL: chainsaw/monolithic-receivers-tls (207.08s)

It doesn't look directly related to this PR, but this test doesn't fail with other PRs :thinking:

@andreasgerstmayr That test has been flaky on upstream, it has failed with other PRs as well and passes after few retries. It always passed in OCP CI jobs. Resource issues ? It failed in this one also https://github.com/grafana/tempo-operator/pull/1002

[andreasgerstmayr]

hm yeah I just saw it failing with another PR. I'd prefer fixing it upstream, I guess it's just a timeout.

[IshwarKanse]

@andreasgerstmayr Ok, I'll take a look in the morning for that failing one.

I gave it a try with #1005, let's see :)
