Description Marty Wesley 2005-06-23 10:35:24 EDT
+++ This bug was initially created as a clone of Bug #155021 +++

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323
Firefox/1.0.2 Fedora/1.0.2-1.3.1

Description of problem:
An up to date Fedora Core 3 machine mounts my home directory from a
NFSv4-server. When "draging and drop"-copying 100 files at the same time from a
file /tmp/r/a.tar.gz opened in file-roller to a nfs-directory ~/nfscrash10
opened in nautilus, the copying stops after about half of the files showing a
pop-up window with a progress bar.

windows title:

"Copying files."

window content:

"Files copied: 43 of 100
Copying: a47
From: /tmp/fr-XzJiHU/a
To: /nfs/home/others/esjolund/nfscrash10
"
and there is a cancel push-button.

Pressing cancel just makes the window not being repainted.
Any process accesing my nfs home directory hangs from now on. For instance
typing "ls ~" on the command line will just leave the ls-process hanging.

Executing the command "ps auxw", I found out that many of the processes with my
uid are in the "D"-state ( uninterruptible sleep ).

The only way to get out of the situation tend to be to reboot the machine.


Version-Release number of selected component (if applicable):
nfs-utils-1.0.6-52

How reproducible:
Always

Steps to Reproduce:
1. login with kde
2. on the command line type: 
   mkdir ~/nfscrash10
3. on the command line type:
   nautilus ~/nfscrash10
4. on the command line type:
   file-roller /tmp/r/a.tar.gz 
 
  You now see that file-roller expands the a.tar.gz file. File-roller
  will show you the directory "a" which resides in a.tar.gz.
5. open the directory "a" in file-roller. Now the 100 files from a.tar.gz is
visible in file-roller.
6. ctrl-a (select all)
7. press left mouse button and drag the files to the nautilus window.
8. release left mouse button
   A pop up window shows you the progress of the copying. After copying about 
   half of the files, the copying seems to stop. 
9. Because nothing seems to happen I press cancel in the pop up window.
  


Actual Results:  Processes accessing nfs home directory now hangs. Some
processes are in the 
"D" running state ( uninterruptible sleep ).


Expected Results:  Processes should not hang.



Additional info:

Oxygen is the hostname of my machine ( the nfs client ).

[esjolund@oxygen ~]$ grep nfs /etc/auto.nfs
home  -rw,fstype=nfs4,hard,intr,nosuid,tcp  nfs.sbc.su.se:/home

[esjolund@oxygen ~]$ uname -a
Linux oxygen 2.6.11-1.14_FC3 #1 Thu Apr 7 19:23:49 EDT 2005 i686 i686 i386 GNU/Linux

I also did 

echo t > /proc/sysrq-trigger

The resulting log from /var/log/messages will be attached to the bug report.

It appears we are not recovering from NFS4ERR_DELAY errors.
This will need more investigation...
