RPC related error are very tough to reproduce.


Was able to see error message id for soft-limit.
Message id start with 1200 series quota. However header files says message id start with 1100 series

Will open separate bug for the wrong message id series and error logs which are not available in the current patch.  

Marking this bug verified on build 3.7-1-10.
