workaround, restart the Jenkins pod
oc scale dc/jenkins --replicas=0 -n burrsutter-jenkins
oc scale dc/jenkins --replicas=1 -n burrsutter-jenkins

We were seeings this pre summit after 5 or 6 pipeline runs that included a call out to bayesian. We tried a few things like groovy and java tuning. Perhaps we should look to bump up that Metaspace again fabric8-jenkins/jenkins-openshift-base@2328e5e

@joshuawilson we probably don't need to move this issue to fabric8-ui, it relates to a possible few components of openshift.io but not the UI.

workaround, restart the Jenkins pod
oc scale dc/jenkins --replicas=0 -n burrsutter-jenkins
oc scale dc/jenkins --replicas=1 -n burrsutter-jenkins

I can confirm that the workaround helps. @sbose78 could you please add it to your FAQ doc if it's not there yet.

@rawlingsj you may continue to comment on it here, I only copy it over so that it gets more visibility. It should only be closed when the issue is resolved. Addtionally, I can copy it to any other repo that you think needs visibility into it. :)

I have now found that oc scale dc/jenkins --replicas=0 -n burrsutter-jenkins
no longer works, you need to "oc delete pod jenkins-1231 --now -n burrsutter-jenkins" to give it more gas to run with.
