Re: df stuck in tstile

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

The solution to this one was on a remote NFS mount.  The remote
machine was being prepared for renumbering but had silently rebooted,
meaning its original IP address was no longer live as it had been
removed from /etc/ifconfig.xxx.  So a plain df hung, /etc/daily hung,
etc. etc.

Aliasing the original IP address back onto the interface cured the
problem instantly and simultaneously on both the affected servers.

I'm most grateful for the help which led me to the cause, but I still
don't understand what tstile really is :-)
