[please honour Mail-Followup-To:, not subscribed to all lists] Hi, This is a respost of http://docs.freebsd.org/cgi/mid.cgi?20040930172241.GA2882 with some additional information; since I got no response, I'm trying better luck here. Short version: rpc.lockd does not start on a 5.3-BETA6 client against a 4.10-p3 server, the error message is: rpc.lockd: 100024 RPC: Port mapper failure Everything looks ok on the server: 281,p0,0$ uname -srn FreeBSD grummit.biaix.org 4.10-RELEASE-p3 283,p0,0$ sockstat -4 | egrep 'rpc|portmap|nfs|mount' root rpc.stat 114 3 udp4 *:739 *:* root rpc.stat 114 4 tcp4 *:635 *:* root rpc.lock 112 3 udp4 *:844 *:* root rpc.lock 112 4 tcp4 *:628 *:* root nfsd 106 3 tcp4 *:2049 *:* root mountd 104 3 udp4 *:849 *:* root mountd 104 4 tcp4 *:647 *:* daemon portmap 100 3 udp4 *:111 *:* daemon portmap 100 4 tcp4 *:111 *:* And from the client: 319,p0,0$ uname -srn FreeBSD calvin.biaix.org 5.3-BETA6 320,p0,0$ rpcinfo -s grummit program version(s) netid(s) service owner 100000 2 udp,tcp portmapper unknown 100004 2,1 tcp,udp ypserv unknown 100005 1,3 tcp,udp mountd unknown 100003 3,2 tcp,udp nfs unknown 100021 4,3,1 tcp,udp nlockmgr unknown 100024 1 tcp,udp status unknown And I can telnet to the portmapper and nlockmgr ports from calvin to grummit (no firewall/hosts.allow issues). I haven't been able to obtain any debug output from rpc*, only these messages. A datapoint is that even though I get many messages like nfs server grummit:/fs/home/mount: not responding whenever I start gnome, I can still do a 'ls /home'. In the ps output I can see lots of process with "pages locked in core". I have a tcpdump available (server-side) if anyone is interested. This is not related to mpsafenet. What else should I look at to try to locate the issue? tks -- pica
