          4.16.0-ec.5\{code}
      How reproducible:
      {code:none}
          50-60%
      
      It seems to be related to the number of times I have ran our test on a single cluster. Many of our performance tests are on ephemeral clusters - so we build the cluster, run the test, tear down. Currently I have a long lived cluster (1 week old), and I have been running many performance tests against this cluster -- serially. After each test, the previous resources are cleaned up. \{code}
      Steps to Reproduce:
      {code:none}
          1. Use the following cmdline as an example.
          2.  ./bin/amd64/kube-burner-ocp cluster-density-v2 --iterations 90     3. Repeat until issue arises ( usually after 3-4 attempts)./
          \{code}
      Actual results:
      {code:none}
          client-1-5c978b7665-n4tds    0/1     ContainerCreating   0          4h14m
      

      Expected results:

          For the benchmark not to get stuck waiting for this pod. \{code}
