I ran only rpcbind, nfsd and mountd on the file server (no rpc.lockd/rpc.statd). I then had an OS/2 Client mount the filesystem, issue a readdir and then tried to mount the same share from an Linux client. This last mount request never came back, immediately after issueing the mount request the mountd got stuck in state 'ufs' as shown in the backtrace. A tcpdump of the session can be found at: http://coyote.dnsalias.net/rpc.pcap (9kB) Uli PS: Please trim the Email when responding to the GNATS DB as that makes the PR-Trail rather unreadable. Thanks!
