Re: [Gtk-gnutella-users] Re: gtk-gnutella freezes during sha1 calculations

well, I can't say for sure what your specific problem might involve,
but I can say that from my experience, what you are describing IS
indeed an NFS problem....
  I don't run Gtkg all the time from my laptop, but when I am working
from home i have my laptop hooked up to my LAN which provides some
NFS shares.  I have found that if I unplug the ethernet cable when
I take it on the road and then try to do simple commands like 'du',
'ls', etc, the terminal window that those commands were run in hangs.
After a period of several minutes I notice my CPU usage meter steadily
increase and finally i cannot run any commands from any window, nor can
i log in to a new session, and eventually have to reboot.
  I would suggest you try the same thing with your computer... not
running Gtkg, and disconnecting your ether cable after establishing
a NFS share... and see if you get the same results.
  My guess is that you will, and hopefully should show you that this
is not something CAUSED by Gtkg, but rather Gtkg does also fall victim
to this NFS problem.
