Strange behaviour from the 'cat' command with NFS

Hello,

One of my user has discovered the following problem on a Digital Unix 3.0
computer.

He has two files f1 and f2 and issues the command :

cat f1 f2 > f1
the answer is immediate :

cat: input t1 is output

but with the command :

cat f2 f1 > f1
there is no answer and when he uses CTRL-C he sees that there is a RECURSIVE
concatenation of the file f1 to itself.

The users's directory is on a NFS mounted file system and the server is an
Ultrix 4.4 computer.

I've tried the same commands on a local filesystem and there is no problem. So
it seems that NFS has an influence on the bug in 'cat'.

Daniel
