Is it possible to get EPIPE from write() to a file descriptor on an NFS disk?

Question

My C++ application seems to have gotten an EPIPE errno result after a failing call to write(). The file descriptor passed to write() is for a file on an NFS mounted disk.

The man page for write() describes EPIPE with:

fd is connected to a pipe or socket whose reading end is closed.  When this
happens the writing process will also receive a SIGPIPE signal.  (Thus, the write
return value is seen only if the program catches, blocks or ignores this signal.)

So I am confused as to how I would get EPIPE. Could it be that this is a multi-threading issue and the errno is incorrectly being supplied for a different thread? I thought errno is thread safe, so that seems unlikely, but then getting EPIPE seems to make no sense. This is on Centos v4.
