[Pacemaker] Failed in restart of Corosync.

Hi,

I understand that a combination is not official in Corosync and Pacemaker.
However, I contributed it because I thought that it was important that I reported a problem.

I started next combination Corosync.(on Redhat5.4(x86))

* corosync trunk 2530
* Cluster-Resource-Agents-6d652f7cf9d8
* Reusable-Cluster-Components-4edc8f99701c
* Pacemaker-1-0-de2a3778ace7

I stopped service(corosync) next.
But, I did KILL of a process because a process of Pacemaker did not stop well.

I started Corosync again.
But, a cib process of Pacemaker seems not to be able to communicate with Corosync.

On this account it does not start definitely even if Pacemaker waits till when.

As for the problem, Corosync seems to fail in poll(?) somehow or other.
However, possibly the cause may depend on the failure of the first stop.

------------------------------------------------------------------------------------
[root at rh54-1 ~]# ps -ef |grep coro
root      5348     1  0 10:55 ?        00:00:00 /usr/sbin/corosync
root      5400  4617  0 10:56 pts/0    00:00:00 grep coro
[root at rh54-1 ~]# strace -p 5348
Process 5348 attached - interrupt to quit
futex(0x805c8c0, FUTEX_WAIT_PRIVATE, 2, NULL
------------------------------------------------------------------------------------

Is there a method with the avoidance of this phenomenon what it is?
Can I evade a problem by deleting some file?

* I hope it so that a combination of Corosync and Pacemaker becomes the practical use early.

Best Regards,
Hideo Yamauchi.
