also maybe you are hitting same problem as was discussed on list in 
thread (Corosync: 100% cpu (corosync 2.3.5, libqb 0.17.1, pacemaker 1.1.13)

Solution is ether apply 7f56f58 on libqb 0.17.1 (see 
https://github.com/ClusterLabs/libqb/issues/139 and 
https://github.com/ClusterLabs/libqb/pull/141), or upgrade to 0.17.2.

Regards,
   Honza
