Actually, I had also reported the memory issue[1] days ago.
Memory exhaust happens because so little 4K memory is allocated for system/software load.

Hi Frank,
We had a zoom call with Al Bailey to troubleshoot the issues that we are observing. The bug where a single CPU was taking all of the workload is resolved.
What we observed seems to be an issue with memory exhaust, additional information was gathered an added to this bug for further troubleshooting:

If additional information is required, please, just let us know.
Thanks & Regards,

Maria:
 
It looks like the commit referenced yesterday [1] is not addressing the issue in your BM labs.  Can you set up a live debug session so that some container SMEs can investigate?
