yep exact same issue

# strace tail -f file
...
inotify_init()                          = 4
inotify_add_watch(4, "file",
IN_MODIFY|IN_ATTRIB|IN_DELETE_SELF|IN_MOVE_SELF) = -1 ENOSPC (No space
left on device)
open("/usr/share/locale/locale.alias", O_RDONLY) = 5
....

looks like I am using coreutils 8.5
iqbala at ghar-iqbala:~$ apt-cache policy coreutils
coreutils:
  Installed: 8.5-1ubuntu6
  Candidate: 8.5-1ubuntu6
  Version table:
 *** 8.5-1ubuntu6 0
        500 http://archive.ubuntu.com/ubuntu/ natty/main amd64 Packages
        100 /var/lib/dpkg/status

So I upgraded to latest coreutils using ppa
iqbala at ghar-iqbala:~$ sudo add-apt-repository ppa:hggdh2/ppa
iqbala at ghar-iqbala:~$ sudo apt-get update
iqbala at ghar-iqbala:~$ sudo apt-get install coreutils
iqbala at ghar-iqbala:~$ sudo apt-cache policy coreutils
coreutils:
  Installed: 8.12.65-5c5576~20110530~ppa1
  Candidate: 8.12.65-5c5576~20110530~ppa1
  Version table:
 *** 8.12.65-5c5576~20110530~ppa1 0
        500 http://ppa.launchpad.net/hggdh2/ppa/ubuntu/ natty/main
amd64 Packages
        100 /var/lib/dpkg/status
     8.5-1ubuntu6 0
        500 http://archive.ubuntu.com/ubuntu/ natty/main amd64 Packages

Now I truly get the inotify message
iqbala at ghar-iqbala:~$ tail -f file
this is a file
tail: inotify resources exhausted
tail: inotify cannot be used, reverting to polling

So why am I still getting this
iqbala at ghar-iqbala:~$ cat /proc/sys/fs/inotify/max_user_watches
8192

what is using inotify? how do I fix it?
