Description of problem: ======================= While trying to access .snaps from NFS mount, snapd and NFS server stopped on the node(from which the volume was mounted) Snapd stopped due to "Request received from non-priviliged port" Version-Release number of selected component (if applicable): ============================================================ glusterfs 3.6.0.32 How reproducible: ================= 1/1 Steps to Reproduce: ================== 1)Fuse and NFS mount a 2x2 dist-rep volume , and enble USS 2) Create 256 snapshots in a loop while IO is going on for i in {1..150} ; do cp -rvf /var/log/glusterfs f_log.$i ; done for i in {1..150} ; do cp -rvf /var/log/glusterfs n_log.$i ; done 3) After snapshot creation is complete, cd to .snaps from fuse and NFS mount From fuse mount, .snaps was accessible , then while accessing .snaps from NFS mount, failed with IO error 4) Checked gluster v status of the volume, showed snapd on the server (thro which the volume was mounted) was down Log messages reported : ~~~~~~~~~~~~~~~~~~~~~~ [2014-11-12 13:32:35.074996] E [rpcsvc.c:617:rpcsvc_handle_rpc_call] 0-glusterd: Request received from non-privileged port.

From Fuse mount, it was successful, but from NFS mount cd to .snaps was hung Actual results: ============== While trying to access .snaps from NFS mount, snapd and NFS server stopped on one node Expected results: ================= Accessing .snaps from Fuse and NFS mount should be successful Additional info:
