Hi Everyone,

We have got a problem with NFS hanging with automounter mounts.

We're running RH8 2.4.20-20.0 kernel
NFS-utils 1.0.1-2
Autofs4.1.2 (we must have the /net ability)
H/W is mixed HP4100's, Dell 2650's, Sun V60 and V65's
All the machines are in a Sun NIS domain with 700 Sun machines that run
fine.

The problem is intermittent; any automounter point can hang at any time.
For example auto_home may have 1000 entries
cd /home/user1 hangs and /home/user2 does not on machine Foo, but
/home/user2 is fine on machine Bar.

Once hung we sometimes can get it to release by umount -at nfs others
time a reboot is the only way to get it to release.

any help is appreciated

thanks,

alan
