The error message means batch thread pool does not have sufficient number of threads available. Can you check your batch subsystem config (subsystem/batch-jberet/thread-pool/max-threads)? Are there large number of job executions that may have exhause the pool of threads?

Another fator is, since you're in openshift, is the quota imposed by openshift for the pod. You can try raising the cpu quota and see if that makes a difference.

[cedricwalter]

you were right, the quota imposed by openshift for the pod was way too low, setting it to 2000m or 2 cores fixes the issues
