Description of problem:

On Solaris Client (SunOS 5.10), under heavy load (lot of folders and files) , the mount point seems to disconnect
mount -o proto=tcp,vers=3,llock,hard,bg,timeo=600,intr,rsize=32768,wsize=32768 nfs://ylal3510/poolsave /users/glusterfs_mnt

glusterfs_mnt>ls
yval8250  yval9000  yvasj200  yvasj410 

:/users/glusterfs_mnt>cp -pr yval9000 testnfs/
NFS server ylal3510 not responding still trying  <= after a while

glusterfs_mnt>ls
testnfs   yval8250  yval9000  yvasj200  yvasj410    <= strange because everything seems ok, mount point still here

/users/glusterfs_mnt>rm -r testnfs
NFS server ylal3510 not responding still trying    <= Instantly
