Description of problem: After compute node reboot, there is bulk_pull error and the instances lose connectivity. The suggestions as per bugzilla: 2212348 did not help Version-Release number of selected component (if applicable): 13 How reproducible: The case is re-opened. From the suggestions we have provided in Comment-3, customer could only perform increase of rpc_response_timeout and he that did not help. Below are the steps customer has performed. - Reboot of the compute node and bulk pull is observed. - Increased rpc_response_timeout and restarted neutron, ovsagent and neutron-sriov containers. That did not help - Customer has to re-deploy the instances to restore the connectivity. I have asked for the possibility of upgrade as this is not on the latest version of OSP-13, and I got the reply that "Red Hat OpenStack software" running in custom containers and without OSP Director, whereas the upgrade has to be performed using their custom CVIM software.
