[Xorp-users] Issue in BGP Configuration

Hi,

That looks very strange, it appears your xorp_bgp process is listening 
on 127.0.0.1:19999, which is normally reserved for the Finder. DNS 
resolution does not appear to be the issue.

To go back to the original issue:
    What you reported in logs normally happens if the Router Manager is 
not able to deal with an incoming XORPSH session right away, usually 
because it's busy dealing with bringing up processes such as xorp_bgp.

    I think you are going to need to build XORP with debugging symbols, 
and forcibly grab a core dump when xorp_bgp wedges like this.

    To do this, you'd run the router as normal. When the BGP process 
hangs, use 'gdb xorp_bgp <pid>'  to attach to the process. Execute 
command 'bt' and send the output to the list, so it is known where 
exactly in the code BGP is hanging.

thanks
BMS
