Very odd problem.  I suspect a networking problem (e.g., DNS
server, firewall IP rules).

It looks like your TCP stack is set-up for a 10 second timeout.
That seems a little short (30 seconds is more reasonable).

Can you ping(1) ldm-11 from webdata-1?  How long does it take?

Please send me the output from the command "ldmping localhost"
on the system on which it doesn't work.  Give the output two
minutes to accumulation.

Regards,
Steve Emmerson
