I stumbled upon this issue when running the quickstarts test, namely with https://github.com/openshift-integration/camel-k-example-event-streaming, I didn't see it in any other test/quickstart (therefore I didn't set it as a blocker, as I don't know how likely the issue is, but definitely something strange is going on with 1.8 and it didn't happen with 1.6).

For some reason, after creating UserReportSystem integration from the mentioned quickstart:

two integration pods are created simultaneously, where at least one of them crashes with:

after that, approximately every 0.5 seconds a new integration pod is started, for example, after ~4 minutes I have:

... a lot more

The minimal working example I was able to create is:

0. deploy serverless operator + knative eventing + knative serving
1. create a fresh namespace
2. install camel-k 1.8 operator, for example kamel install --maven-repository="<some repository with necessary artifacts>" --olm=false --operator-image registry-proxy.engineering.redhat.com/rh-osbs/integration-camel-k-rhel8-operator:1.8.0-10
3. as mentioned in the quickstart, create the secret oc create secret generic example-event-streaming-user-reporting --from-file=application.properties
4. create the channel with kn channel create audit --type imc
5. create the user-report-system integration kamel run UserReportSystem.java
