Dave,
is that segfault reliable? I was trying following script on same svn
revision of trunk and cman_tool + fenced + ... from todays stable3:

#!/bin/bash

for i in `seq 1 100`;do
    ssh root at 192.168.64.101  'service cman start' &
    ssh root at 192.168.64.102  'service cman start' &
    ssh root at 192.168.64.103  'service cman start' &
    ssh root at 192.168.64.104  'service cman start' &
    sleep 20
    ssh root at 192.168.64.101  'service cman stop'
    ssh root at 192.168.64.102  'service cman stop'
    ssh root at 192.168.64.103  'service cman stop'
    ssh root at 192.168.64.104  'service cman stop'
done

I was not able to get that segfault.

Can you please compress core file and send it/put it somewhere on web
(choose which one you like more)?

Regards,
  Honza
