Description Adam 2000-06-10 16:50:00 UTC

when you do:
mount <ip>:/mountpoint /mountpoint 
it dosent register that its mounted
If you do this ~131 will make TOTAL SYSTEM LOCKUP with CONSOLE REBOOT
...yes i was bored =)
This could also lead to a mount problem with 131 mount points too. god forbid...

Fix: 

Do checking on NFS mounts
How-To-Repeat: mount ip:/point /point

The ability to stack multiple filesystems over a single mountpoint 
is a feature, not a bug (maybe `mount -a' could handle this better 
though). 

Can you confirm whether or not the lockups/reboots still occur on 
a recent -stable? I cannot repeat this problem. With around 450 
NFS mounts over one mountpoint I ran out of reserved ports so the 
remote mountd stopped accepting the connections, but I experienced 
no crashes or lockups.
