Node restarts take a very long time

[bdaoudtdc]

Describe the bug

We have a cluster of 3 nodes.
All our queues are quorum queues.
If we change any of the config parameters in the YAML file , node restarts may take between 10-40 mins
It takes a very long time to terminate a pod.
The time taken for terminating a pod is random and the long time is not happening on any particular pod.
It may happen on any of the 3 nodes.

Expected behavior
That restart takes less than 3-4 mins of all nodes

I will convert this issue to a GitHub discussion. Currently GitHub will automatically close and lock the issue even though your question will be transferred and responded to elsewhere. This is to let you know that we do not intend to ignore this but this is how the current GitHub conversion mechanism makes it seem for the users :(
