Could you please look into this one?

The commit f1a4b79e378407e4161c2a922478d625a38452b5 already remove the big rpc in 101c, So looks like this issue can be ignore? Maybe WangDi has some point for that.

[Di Wang]

Yes, that check is not correct. The patch for lu-983(http://review.whamcloud.com/#change,1998) will remove that check.

[Yang Sheng]

AS WangDi's comment, close it.
