Need to check with NFS team for the meaning of this.
I could hit the same issue with multiple rename operations. Distriubute setup with 4 nodes.
That generally means that the NFS server is sending duplicate continuation cookies in READDIR calls. Note though that there is a bug in recent RHEL6 client kernels that can make this message pop more frequently than it should. See bug 770250.
Can you please confirm if this bug is seen with RHEL 5.x clients?
Not seen with 5.x clients. Hence removing the target milestone.
Raghavendra Bhat (rabhat) didn't see it in any recent versions. Would like it to be tested with 3.4.0qa branches to see if its seen again.
Testing with 3.4.0qa4, will update after a few runs.
