Did ccsd die as well?
Comment 2 Lenny Maiorani 2006-05-17 11:06:44 EDT
Nothing else died. The node was still running OK after the segfault.
Comment 3 Lon Hohberger 2006-05-17 11:37:06 EDT
Thank you -- I will keep looking; so far, I have not been able to reporduce it,
so I think it is a timing issue of some sort (eg - getting a member list while
cman is handling the transition).
Comment 4 Lenny Maiorani 2006-06-07 18:24:52 EDT
I think the new rgmanager (now using 1.9.46-1.4.2x) has fixed this.
