Your running this under a Xen domU right? You could try the i386 versions to see, but I wouldn't be surprised if you end up with the same results. Instead of a domU why not try running it out of an HVM which performs greater level of abstraction. IF heartbeat is trying to use the low level features of the network interface then that may be the reason it is segfaulting in the para-virtualized machine. > > > > So, in summary, from my experience: > > > > 1. forget RCS > > 2. use Heartbeat in version 2 mode to control both LVS and > REAL Server > > functionality. > > 3.
