You might be able to see NFS flooding with: Write file on client. rm the file during the write on the server. The client now gets IO-errors, but keeps trying forever. Maybe it depends on the mechanism the client application uses to write the file. I never reported because my client is an old 7.0-stable system. I originally noticed it when downloading files with seamonkey on my client and mv it on the server to another partition before it was completely downloaded. -- B.Walter <[email protected]> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
