```

The liveness probe's configuration:
```
    livenessProbe:
      exec:
        command:
        - grpc_health_probe
        - -addr=:50051
      failureThreshold: 3
      initialDelaySeconds: 10
      periodSeconds: 10
      successThreshold: 1
      timeoutSeconds: 1
```

The probe is configured to be ran every 10s. Correlating with the "Probe failed" logs from the ci-op-k72hr7js-f0f18-wpzls-worker-a-qtzrv node, the probe does not fail consistently every 10s. E.g.:
```

```

So it's likely the container itself does not always respond to grpc_health_probe in time. The issue looks similar to https://bugzilla.redhat.com/show_bug.cgi?id=1815957#c6 described as:
```
The issue is that on some systems, a lack of an nsswitch config means that dns will attempt to resolve from external sources before local files (so resolving `localhost` could take a long time).
```

Comment 2 Evan Cordell 2021-06-28 22:08:49 UTC
The images in question will start up and write out an nsswitch config to avoid the slow resolution problem, I doubt that is the issue (unless there's been some regression related to nsswitch)

There are two options that seems possible/likely:

1.grpc_health_probe is slow to respond inside the container
2. CRI-O itself is timing out on ExecSync

(1) is possible, but I'm skeptical of it just because of the long timeouts / retries used. They're really generous, and the api should be available almost immediately on container start. To investigate more, I think we should instrument the index pods with grpc metrics and see if we can get data on what the probes are seeing.

(2) is starting to seem more likely to me, especially because via CI search I can see this issue affecting SNO clusters at a much higher rate than other clusters configurations (where CRI-O would have the highest contention). Unfortunately CRI-O metrics are not enabled in openshift, so I can't see any latency/load data during cluster boot.

I think both are worth further investigation, and I'd like to enlist some node folks to help investigate in case (2) seems plausible. My read of kubelet is that we can't distinguish between the two cases based on the audit logs alone: https://github.com/kubernetes/kubernetes/blob/397ff0b3cb2d674113f3cb8195e044ebdf88d27b/pkg/kubelet/cri/remote/remote_runtime.go#L396-L399

*** Bug 1977241 has been marked as a duplicate of this bug. ***

Comment 4 Evan Cordell 2021-06-29 20:41:16 UTC
Updating based on further investigation:

the issue seems to be simple cpu contention in the probe, which is more likely in SNO clusters during boot. increasing the timeout should resolve the CI issues - this is not an issue for running clusters, since eventually the pods restart at a time when there is not contention and can respond to the probes.

Comment 5 Anik 2021-06-29 20:43:52 UTC
It is highly plausible that the "crio is timing out" issue mentioned by Evan is the likely cause here. In the absence of crio metrics, observing a cluster that had the alert firing during cluster bootstrap (deduced from the restarting registry pods in the openshift-marketplace namespace before eventually running successfully):

```

looks like it takes a while for the registry pods to eventually start running. This was likely happening all along, but started getting highlighted in the ci when prometheus alerts for default CatalogSources in the openshift-marketplace namespace were introduced as part of https://bugzilla.redhat.com/show_bug.cgi?id=1973482. 

The fix PR linked in the bz bumps up the values of the initial delay seconds and timeout seconds of the liveness probe of the registry pods, after consultation with the node team that the default value of 1s for liveness probe timeout is likely not enough when there is a resource constraint.

Comment 6 Anik 2021-06-29 20:46:55 UTC
> the issue seems to be simple cpu contention in the probe

that sounds reasonable too. The fix remains the same though.

Comment 9 Artyom 2021-06-30 12:06:32 UTC
But it better than under 4.8, so probably we can increase a little bit more the timeout and cherry-pick it to 4.8

Comment 10 Anik 2021-06-30 14:07:07 UTC
Arytom, looks like the PR merged around 12:00 UTC, so around the same time you saw those failures. I'm guessing it would have taken a while for the PR to show up in ci builds. Probably need to verify if the PR was included in the builds for the failures you saw. We'll also get more information from amortized results from ci-search/ci test grids than individual PRs.

Comment 11 Artyom 2021-06-30 15:28:08 UTC
Sorry missed it, thanks for the information will wait for the next run.

Comment 12 Tom Buskey 2021-06-30 17:52:08 UTC
I'm not sure if this has the PR in it.  Do you have a link?

Once my run finished and the cluster was quiescent, I stopped seeing probe failures running oc get events -n openshift-marketplace -w

Hi Tom,

> I'm not sure if this has the PR in it.  Do you have a link?

The fixed PR is https://github.com/openshift/operator-framework-olm/pull/106, and it was merged in commit 121f35e9, details: https://github.com/openshift/operator-framework-olm/commits/master  

So you need to check the OLM commits info, there are 2 ways:

1, Check the cluster payload, as follows:

[cloud-user@preserve-olm-env jian]$ oc adm release info registry.ci.openshift.org/ocp/release:4.9.0-0.nightly-2021-06-30-123441 --commits|grep lifecycle
  operator-lifecycle-manager                     https://github.com/openshift/operator-framework-olm                         2a45f52303b05d6d02766c4ee76758881fc14522

2, Check the OLM version:
[cloud-user@preserve-olm-env jian]$ oc -n openshift-operator-lifecycle-manager exec deployment/catalog-operator -- olm --version
OLM version: 0.17.0
git commit: 2a45f52303b05d6d02766c4ee76758881fc14522

Obviously, this commit(2a45f52303b05d6d02766c4ee76758881fc14522) is before the PR merged commit(121f35e9), so the payload "4.9.0-0.nightly-2021-06-30-123441" doesn't have that fixed PR.
