>> Is there a specific log to look into to see the freeze up, most of the logs I’ve checked out have tons of information but not sure what I am searching for as the culprit

I would first look in the mgmt's ( and subsequently the other component's) localhost logs to determine which request is causing the issue. Once you narrow down the request; you can look in the code/try adding additional log statements etc. Check for anything related to out of memory etc. Does restarting fix this issue temporarily? Also, did you check the browser's console log for any client side exception?

>> but it just will not return anything status wise about the PV search.
I think most of this is done in memory on the mgmt instance. However; the cluster needs to be active and alive for this to work correctly. So any info on actions that takes the cluster down ( out of memory, for example) would help.

Murali
