      E0221 20:29:52.377443       1 controller.go:182] csr-dm7zr: Pending CSRs: 1871; Max pending allowed: 604. Difference between pending CSRs and machines > 100. Ignoring all CSRs as too many recent pending CSRs seen

      .

      oc get csr |wc -l
3818
oc get csr |grep "node-bootstrapper" |wc -l
2152

      By approving the pending CSR manually I can get the cluster to scaleup.

      We can increase the maxPending to a higher number https://github.com/openshift/cluster-machine-approver/blob/2d68698410d7e6239dafa6749cc454272508db19/pkg/controller/controller.go#L330
