Is there anyway to achieve > this setup if not with Heartbeat with some sort of other HA solution? (Bear in mind - I'm talking about Heartbeat V1 config style here, not v2/3.) I've used mon successfully to enable that. You can add mon as a clustered resource in addition to apache, then configure mon to look for the apache process. If it finds that httpd isn't running, it will kill the heartbeat process, thereby forcing a failover. In Heartbeat V2/3, I believe that pacemaker does something similar, though I'm not certain, as I'm mortally allergic to xml-based config files that have been massively overbuilt. ;) -I
