Hi,
We are using a 3-node pacemaker/corosync cluster on CentOs 7.
We have several identical setups in our QA/DEV orgs, and a couple of them continuously spew the following messages on all 3 nodes:
Oct 8 17:18:20 42-hw-rig4-L3-2 corosync[15105]: [TOTEM ] A new membership (10.1.13.134:1553572) was formed. Members

The cluster seems to be generally happy:

}
quorum {

}
logging {

}
What do these messages mean, and how can we stop them?
Any help would be very appreciated.

PS
I have tried to enable corosync debug and got the following logs:
