I'm currently seeing an NFS-hang, which will probably cause me to reboot an otherwise happy system. A java process was overwriting files in an NFS-mounted directory, when I tried to Ctrl-C it (always worked before). The process is now hung in "nfrslk" state: load: 1.65 cmd: java 53499 [nfrslk] 0.07u 0.02s 0% 8956k An attempt at regular umount of the filesystem is hanging in "nfs" state: % umount /tmp/.a/beaker/host/beaker load: 1.33 cmd: umount 53521 [nfs] 0.00u 0.07s 0% 820k A subsequent attempt at forced umount is in "vfs_busy": % umount -f /tmp/.a/beaker/host/beaker load: 1.33 cmd: umount 53526 [vfs_busy] 0.00u 0.05s 0% 644k I have restarted the /etc/rc.d/nfslocking and /etc/rc.d/nfsclient -- no change. How can I help fix this problem? I'm using 5.4-STABLE as of July 7th. Thanks! -mi
