** Description changed: I get several "NFS: directory xxx contains a readdir loop.Please contact your server vendor. Offending cookie:xxx" on the client side of an NFS4 mount. I have tried several different kernels 3.0.xx with the same result (currently using . I am using autofs. Issue seems to be related to the large number of files (with a high rotation as well). ls | wc -l gives >100,000 files. Bug is intermittent, software tries to access the files with success some times, and failure other times (exact same usage pattern). The software fails with " Too many levels of symbolic links". No errors appear on the server log. It appears to be the same issue as reported here: https://bugzilla.redhat.com/show_bug.cgi?id=790729 uname -a Linux uruk 3.0.0-22-server #36-Ubuntu SMP Tue Jun 12 17:56:20 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Extra info: 1.- lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 2.-apt-cache policy linux-image linux-image: Installed: (none) Candidate: 3.0.0.23.27 Version table: 3.0.0.23.27 0 500 http://gb.archive.ubuntu.com/ubuntu/ oneiric-updates/main amd64 Packages 3.0.0.22.26 0 500 http://security.ubuntu.com/ubuntu/ oneiric-security/main amd64 Packages 3.0.0.12.14 0 500 http://gb.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages 3.- I expect the software to access the files and no readdir loop errors to occur 4.- Software fails with Too many levels of symbolic links, kernel logs NFS: directory xxx contains a readdir loop.Please contact your server vendor.
