@sandeep-krishnamurthy I notice there is another PR (#13952) working on the fix. I would hope that PR can be merged soon and then we don't need a hot fix for the issue. @xinyu-intel Please confirm, thank you.

[xinyu-intel]

@sandeep-krishnamurthy @TaoLv Yes, #13952 can fix this. I'll close it once #13952 merged.
