[1.] One line summary of the problem:
Problem when using a nfs mounted filesystem.
[2.] Full description of the problem/report:
I mounted a remote filesystem on my machine with the following command:
[root@localhost mnt]# mount -t nfs -o "hard,intr,nodev,nosuid" hats105:/export1 /mnt/export1
[root@localhost mnt]# df -ak Filesystem 1k-blocks Used Available Use% Mounted on /dev/hda1 1597004 141176 1374704 10% / none 0 0 0 - /proc devfs 0 0 0 - /dev none 0 0 0 - /dev/pts none 127620 0 127620 0% /dev/shm /dev/hda9 8380704 18944 7936040 1% /home /dev/hda8 6720216 123056 6255784 2% /tmp /dev/hda6 10381004 2282880 7570792 24% /usr /dev/hda7 12096724 18664 11463576 1% /usr/local hats105:/export1 4113280 1476736 2595392 37% /mnt/export1
Everything seems OK for a while since I can access any directory/file under /mnt/export1. Suddenly, after a few minutes, I cannot access anymore this file system. All my programs which where using these filesystems are frozen and I they dont even receive any signals. I cannot umount this filesystem neither. I checked the nfs server is still up and running so the problem seems to come from the client side.
