Use both connections for heartbeat. Maybe use ucast on the external 
interface instead of bcast.

Your supplied config file only reads one interface:
--------------
*ha.cf:

use_logd yes
compression zlib
coredumps no
keepalive 1
warntime 2
deadtime 5
deadping 5
udpport 694
bcast eth2
node test-ppc test3
ping 192.168.122.113
#respawn hacluster /rnd/apps/components/heartbeat/lib/heartbeat/ipfail
#respawn root /rnd/apps/components/heartbeat/lib/heartbeat/pingd -m 100 -d
5s
#auto_failback off
crm yes
-------------

But if it really is the way you tell, this should not cause the problem 
you told about.

Just a thought: If - by any chance - you pull the plug out of the 
connection that sends/receives the heartbeats, you will have a 
splitbrain situation which would nicely explain the things you mentioned.

So please use both links for heartbeat cluster communication and make 
sure you pull the right plug :)
