Hitting Igor's Caching Thresholds

Issue​

Completing a Jenkins job doesn’t trigger a pipeline execution. Pushing to a docker repository doesn’t trigger a pipeline execution In your Igor logs, you see something like: Number of items (999999) to cache exceeds upper threshold (1000) in monitor=DockerMonitor partition=dockerhub

Or: Number of items (999999) to cache exceeds upper threshold (1000) in monitor=JenkinsMonitor partition=jenkins

Cause​

Potential causes could be:

  • A new Jenkins master has been added* A new docker registry has been added* Igor has been down for a while* Redis has been wiped
