Hello, Ben.

Here is the way how I reproduce this:

# invoke-rc.d xorp start
Starting eXtensible Open Router Platform : xorp.
# xorpsh
Welcome to XORP v1.8.5-WIP on cmegw
Version tag: 00000000  Build Date: 2012-01-11 00:01 32-bit
root at cmegw> show pim neighbors
Interface    DRpriority NeighborAddr    V Mode   Holdtime Timeout
cme-gw                1 10.145.2.221    2 Sparse      105      98
root at cmegw>
(Push Ctrl+D)
End of connection.
# sleep 60
# xorpsh
(Hangs here, uses all CPU resources)

I can reproduce this almost all the time. Interesting thing: If I omit
sleep command and run xorpsh right after startup then I cannot
reproduce the bug for some time. There is no difference wether I exit
with EOF or with "quit" command.

Startup logs and configuration file can be found on
