Hi Jiaju,

I have a question about booth.
I structure 2 sites and 1 arbitrator. And each site consist of 2
node(ACT node and STB node).
Firstly, I kill corosync in one node. This node have a booth and a ticket.
Then booth is fail-over to STB node. The site including this node
always have a ticket.
However, an another site is granted at the same time.  Therefore, 2
sites was granted.

I guess that sites cause fail-over because of a ticket was out of
expire date in synchronized timing.
However, I not see any reason to be granted 2 sites.  Are you correct
this behavior?

A following information is each site of ticket information after this
case was caused.

siteA:<ticket_state id="ticketA" owner="2" expires="1340255934"
ballot="2" granted="true" last-granted="1340255142"/>
siteB:<ticket_state id="ticketA" owner="2" expires="1340255933"
ballot="2" granted="true" last-granted="1340255441"/>
siteC(arbitrator):<ticket_state id="ticketA" owner="2"
expires="1340255934" ballot="2" granted="false"/>

Sincerely,
Yuichi
