Revert "Bug fix channel utilization during high traffic"

This reverts commit 2800851c885bd0f228e42a587c1db33da98f29ce.

Reason for revert: the merged CL has a wrong Merged-In which prevents the CL being auto-merged to other RVC branches including mainline-prod. Will re-submit a new CL with correct Merged-In so that it can be still auto-merged to other RVC branches but not into master.
