Hi all,

Apologize for the trouble!
And Many thanks for you all for the report!
Obviously, I missed memory stress testing which I should do. Apologize again!

Qian Cai,
Which test case are you using? Could you share the reproduce steps for me?

Hugh,
Many thanks for help! I will seek some memory stress case and waiting for your case.


Thank you all!
Alex
