I have two computers running linux 1.2.13. One of them is a nfs-server, and
the other mounts a filesystem from it. Version of nfs-server is "universal
nfs-server 2.0". I have written a program, which writes data on both
computers (for security). Filesystem is mounted with "defaults,soft" option,
so I can detect situations like break in the wire (IO error in write ()),
warn the user and continue the operation writing only on one filesystem.
But I have noticed that functions write() or open() return sometimes EAGAIN
error (try again). 

WHAT DOES THAT MEAN ?? What can be a cause of that ?

Jacek
