- Hi all,
- I have a writer program that runs in the background waiting to
- open(<namedpipe>, O_WRONLY). When somebody tries to cat the
- <namedpipe>, the writer wakes up, does its thing and close()s.
- Then it goes back to the open() call, blocks waiting for the
- next reader, etc.
-
- The problem happens when the <namedpipe> is on an NFS mounted
- filesystem. The writer only wakes up for readers running on its
- processor. Remote readers hang. I thought that running the
- writer on the NFS server would solve the problem, but no.
-
- Any ideas? Thanks.
