Description Andre Costa 2022-08-10 15:11:34 UTC 
Description of problem:
This BZ is a spin-off of BZ-2114945 so we can track possible issues with new TCP connections from pods failing to be created on the nodes leading to pods being unable to start or crash.

Version-Release number of selected component (if applicable):
OCP 4.10.24 with OVN-Kubernetes

How reproducible:
Periodically on the customer only so far.
