The problem seems to be in readdir or perhaps stat. I can't ls :a directory that's mounted via UDP. I can read files. The problem :goes away with TCP mounts. I had problems with both FBSD 4.4 and Solaris :2.8 clients. The server is new, so I don't have any historical data, :however I've never had problems in the past in other servers using UDP. :The system was cvsup'ed Thursday evening. : :Danny : :-- :Daniel Schales Louisiana Tech University This could be just about anything. I recommend you run tcpdump on both the client and server and observe the NFS packet traffic during the failure. We haven't made any changes to the readdir code specifically. Other possibilities: The ethernet card may have packet loss or may have problems. There may be mtu issues. There may be firewall issues. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
