That's good information.  Either xorpsh isn't handling delayed
accept (ie, EINPROGRESS) or maybe the rtrmgr isn't accepting new
connections properly.

Can you telnet to that port to see of rtrmgr properly allows

telnet localhost 19999

Maybe also strace on rtrmgr while you are attempting xorpsh connect to
see if it ever sees the connection and accepts it?

Here's what I get (I'm running rtrmgr on port 4501 in this case):

[root at ct503-10G-09 lanforge]# telnet localhost 4501
Trying ::1...
telnet: connect to address ::1: Connection refused
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

Here is what I see in the logs:
[ 2010/03/26 09:21:47.581267  ERROR xorp_rtrmgr:18204 FINDER libxipc/finder_tcp.cc:170 read_callback ] Bad input buffer size (1751477356 bytes) from wire, 
dropping connection

Please check to see if you get similar results.

Those are probably not the problem.
