How reproducible: Didn't try to reproduce the issue.


Steps to Reproduce:
1.create and start a geo-rep relationship between master and slave. 
2.create data on master using the command "crefi -n 10 -T 10 --multi -b 10 -d 10 --random --max=50K --min=1K  /mnt/master"
3. Let it sync to slave and do find on slave fusee mount point 

Actual results: Find on slave mount point hung. 


Expected results: Find shouldn't hang on mount point.
