I have uninstall and reinstall all the packages (same versions) and for now
i have no segfaults (at least for the last 45 minutes).
I'm still waiting to see the nodes on crm_mon.
Should i check something? I think it is enough time for the nodes to appear,
so something must be wrong.
I'm attaching the log after the last run of openais.
Thanks again.
