[Linux-cluster] Qdiskd: heuristics not working

Hi,
I'm working with RHCS version
cman.x86_64 2.0.115-68.el5_6.1 installed
openais.x86_64 0.80.6-28.el5 installed
rgmanager.x86_64 2.0.52-9.el5 installed
I've a two node cluster with quorum device. I'm using heuristics to prevent fence death situation. My heuristic was working fine with a previous version of cman.
When I simulated a network partition. I saw the message below:
qdiskd[10657]: <info> Heuristic: '/usr/local/cmcluster/conf/admin/test_hb.sh' DOWN (1/1)
However with the new version of cman, with the same heuristics, if I simulate a network partition, qdiskd doesn't realize and just after totem token timeout I see the message below:
openais[3750]: [TOTEM] The token was lost in the OPERATIONAL state.
The nodes fence each other and my cluster ends powered off. Anyone suffering with quorum heuristics with the latest cman version?
Thanks
Best Regards,
Ana
