[Pacemaker] cib fails to start until host is rebooted

[Michael Smith]

Hi,

I have a pacemaker/corosync setup on a bunch of fully patched SLES11 SP1 
systems. On one of the systems, if I /etc/init.d/openais stop, then 
/etc/init.d/openais start, pacemaker fails to come up:

Aug 30 15:48:09 xen-test1 cib: [5858]: info: crm_cluster_connect: 
Connecting to OpenAIS
Aug 30 15:48:09 xen-test1 cib: [5858]: info: init_ais_connection: 
Creating connection to our AIS plugin

Aug 30 15:48:10 xen-test1 corosync[5851]:  [IPC   ] Invalid IPC credentials.
Aug 30 15:48:10 xen-test1 cib: [5858]: info: init_ais_connection: 
Connection to our AIS plugin (9) failed: unknown (100)

Aug 30 15:48:10 xen-test1 cib: [5858]: CRIT: cib_init: Cannot sign in to 
the cluster... terminating

I've tried rm /var/run/crm/*, but it doesn't help; the only fix is to 
reboot.

I have an strace -f of /etc/init.d/openais start, if that would help.
