The kernel bug only occurred once, so possibly that is less significant. Here is some extra information: if there is anything else I can provide please let me know. (1) The NFS hang has happened on 4 different client computers, all 64-bit machines running SuSE 11.0. Current kernel is kernel-default-2.6.25.11-0.1 (2) So far it has not happened on 32-bit clients, nor on SuSE 10.x clients (3) Typically only one client at a time is affected, other clients continue to work (4) When it happens anybody with an NFS-mounted home directory gets completely stuck, but root can still login. Other network protocols (e.g. ssh) still work (5) Two different NFS servers have been involved, both are running SuSE 10.2 and have been running very smoothly for a year. When the problem occurs it typically only affects communication between one client and one server: the client can still use file systems mounted on the other server. (6) The problem can be resolved by typing strace df umount -fl filesystem mount -o udp filesystem and repeating this for each hung file system. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(2) In each case remounting the file systems as UDP solved the problem and the machines remained stable (3) Recently all the machines needed rebooting to install the latest kernel, so the NFS file systems went back to default protocol settings (4) The problem has reappeared Note that the kernel BUG in the problem summary has only occured once, so possibly is a red herring. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
