Igor, Travis, Thanks for your attention to this issue.
We extended the timeout for the liveness probe yesterday, and also extended the time after which a down OSD deployment is deleted by the operator. Once all the OSD deployments were recreated by the operator, we observed two OSD restarts - which is a much lower rate than earlier. Igor, we are still working on piecing together logs (from our log store) before the OSD restarts and will send them shortly. Thanks.
