# Hitting Igor's Caching Thresholds

### Issue <a href="#issue" id="issue"></a>

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 <a href="#cause" id="cause"></a>

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
