Environment:

# cat /etc/system-release
CentOS release 6.6 (Final)

# corosync -v
Corosync Cluster Engine, version '1.4.7'

# cat /etc/cluster/cluster.conf
<cluster config_version="16" name="lps">
  <fence_daemon/>
  <clusternodes>
    <clusternode name="stlps001-cl" nodeid="1">

      <fence>

    <failoverdomains/>
    <resources/>
  </rm>
  <logging>
    <logging_daemon name="corosync" subsys="TOTEM" debug="on"/>
  </logging>

The interfaces stlps001-cl/stlps002-cl - 2x1Gb bond (crossover cables, bond_mode=802.3ad).
The interfaces stlps001/stlps002 - 10Gb (connected over L2 Switch).

Any ideas?
