Sorry, I forgot it!

I've two connection for the PCs:

one with crossover cable, where heartbeat send packets directly to other PC
one through network, where the services listen and where pingd test
connectivity

When I force the failure I disconnect the network cable that give services
from PC_A.

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 :)
