Bug Description
When testing failover for configured multipath devices, I am seeing some nodes lock up and become unresponsive. These nodes have frozen consoles, but can be pinged. So some of the network stack is functional, but ssh is not possible to them.
1) 20.04 focal
2) 0.8.3-1ubuntu2
3) multipathing failover would be successful across all nodes and the nodes would continue to be responsive
4) some of the nodes lock up when attempting to failover and cannot be reached via ssh or console

Thank you for taking the time to file a bug report.
I went through the logs but I was not able to spot anything that could help us understand the why of your issue. Have you applied any change to the default multipath config file? Could you describe better your scenario? I'd like to gather all the information available before spending time trying to find a reproducer in a virtual environment, which involves setting up a bunch of things.
I am setting the Status of the bug to Incomplete, once you provide more information please set it back to New and our team will take a look at it again.
