> Hi expert:

> I meet a problem when I use glusterfs. The problem is that the fuse client consumes huge memory when write a   lot of files(>million) to the gluster, at last leading to killed by OS oom. The memory the fuse process consumes can up to 100G! I wonder if there are memory leaks in the gluster fuse process, or some other causes. Thanks!
