No space left on device - bug?

[Asif Iqbal]

Hi

I am been noticing this odd error in my ubunut 11.04 64bit.

iqbala at ghar-iqbala:~$ cat file
this is a file
iqbala at ghar-iqbala:~$ tail file
this is a file
iqbala at ghar-iqbala:~$ tail -f file
this is a file
tail: cannot watch `file': No space left on device

I do not have any resource issue. Any suggestion what could be causing
it?  It clears for few mins followed by a reboot. And then re-appears.
