Version-Release number of selected component (if applicable):
3.3.0 & 3.2.6

How reproducible:


Steps to Reproduce:
1.Create a replica volume on server1 and server2.(Number of Bricks: 1 x 2 = 2)
2.Mount volume on client1 and untar kernel to mountpoint.
3.While client is compiling the kernel, set quota on those dirctories which were untared from kernel with value of 100MB each directory.
 
Actual results:
Client will get blocked in a while,not be able to use some commands(eg df, ls "mountpoint").

Expected results:
Compilation will be completed.

While compiling kernel, set quota on around 2000 dirs. Still client was safe from crash.
