• MW Officer: It was found that the new Red Hat kernel 2.6.32-504 that comes with RHEL6.6 and as a security patch for older RHEL6 installations has a bug wrt. fuse. Due to the bug, cvmfs clients that are exported via NFS immediately provoke a kernel panic. The problem is not cvmfs specific but all fuse modules that are exported via NFS are affected. Site's that use the NFS exported cvmfs client must not update to this kernel. The common cvmfs deployment mode as a fuse module on the worker nodes seems not to be affected.
