Hi,

I confirmed movement when corosync1.2.7 combined Pacemaker.

The combination is as follows.

 * corosync 1.2.7
 * Pacemaker-1-0-74392a28b7f3.tar
 * Cluster-Resource-Agents-bfcc4e050a07.tar
 * Reusable-Cluster-Components-8286b46c91e3.tar


I confirmed the next movement in two nodes of a virtual machine(RHEL5.5 x84) and the real
machine(RHEL5.5 x64).
The resource arranged nothing.

1) When it started only in corosync, a node do not be hung up.(and when stopped)
2) When I put Pacemaker and corosync together and started, a node do not be hung up.(and when stopped)

Only 20 number of times carried out the confirmation in each environment.(x86 and x64)

Unfortunately the following problem occurred.
 * The problem did not happen by the start only for corosync this time.(and when stopped)

Problem 1) By the start of the virtual machine, a virtual machine is sometimes hungup.
           Like a former problem, it is used nearly 100% for the CPU.

Problem 2) There was the case that cannot constitute a cluster after start. 

Problem 3) There is a case to fail in the start of a cib process and the attrd process.

Can this problem be settled in Pacemaker1.0 and corosync1.2.7?

I know that a revision to replace communication with CPG in structure of new Pacemaker begins.
When we combine corosync and use it, should we wait for a revision of CPG to be over?
(Should we wait for Pacemaker1.1 system?)

Because log is big, I contact it again after registering this problem with bugzilla.
