Description timlee 1999-08-20 19:10:01 UTC

	NFS hangs during large write through self-NFS mount.
	Couldn't figure out how to fix it without rebooting
	(was able to login (as root) at the console, but not
	(as non-root) through the network).

Fix: 

Workaround is to avoid writing through self-NFS mounts.
	Don't know what actual fix is.
How-To-Repeat: 
	Mount an NFS exported filesystem to the same computer.
	Write a large file through the NFS mount (for example,
	do a mkisofs of a Red Hat 6.0 Linux image with -o pointing
	to a file on the self-NFS mount).

This is a known problem which we believe we have fixed in -current (4.x) 
but which we have not fixed in -stable (3.x).  It may not be possible to 
fix this problem in -stable.   

I've marked the bug report as analyzed but am leaving it open either 
until we find a way to fix in -stable, or until we rotate major releases 
again.

Recently committed fixes to 4.x and 5.x which should solve the 
self-mount problems.
