1.  Linux system hangs when being shared Helios directory is accessed my 
Macintosh client

2.  This is exactly what I am doing.  I have installed Helios Ethershare 
on my linux box.  I am using an iMac (MacOS 9.22) to access the shared 
directories.  This all works fine up until a certain point.

I put in an HFS disc into the local drive on my linux box.  I mount this 
as an HFS disc by doing: "mount -t hfs /dev/hdc /mount_pt_1"

I am then NFS mounting that directory to another directory on the same 
box.  "mount -t nfs localhost:/mount_pt_1 /mount_pt_2".  This works fine 
and can view the contents of the disc over the two mount points perfectly.

The /mount_pt_2 directory is the shared directory from 
Helios Ethershare and will be allowed readonly access by the iMac.  I go 
to the Chooser on the iMac and open up this directory and it just hangs.  
I go back over to the linux box and I can not access that directory 
anymore.  It is hung and have to quit out of my shell.  I can no longer 
umount any of my mounted directories.  I have to reboot.

3.  Keywords:  NFS, HFS, Helios, Ethershare

4.  I tried this on Kernel Version: 2.4.7-10 and also on 2.4.21.  The same 
thing happened on both of them.

5.  OOPS:

  7.7  OTHER INFORMATION:  Kernel 2.4.21 was downloaded and compiled and 
installed.  I added now patches to it whatsoever.  This is a fairly simple 
problem to reproduce I feel.  The only difficulty will be getting Helios 
Ethershare software if you do not have it.  

We are using Ethershare Version 2.6, CD-17.

Please let me know if you need any other information.
