Corosync 1.4.6 is not part of RHEL-6, it's version 1.4.1. Does this happen on a supported version? I build corosync-1.4.6 based on the lastest corosync source code and corosync src rpm package from rhel6. I will make another test on corosync-1.4.1 to make sure whether the bugs exists in 1.4.1. I am so sorry. This bug is caused by the service written by myself. After remove my service from corosync, the corosync works correct again. No problem. Can you close this BZ then please :) The bug missing is an mistake. It is still there.
Because I had open the corefile flag in my service, I can get the corosync crash by the exist of corefile.
After remove my service, there's no corefile generated when corosync is crashed.

Does the my_failed_list or my_proc_list need to be reinitialized after the network interface is up?
