It almost sounds like they are going into a sleep cycle. I get the impression that ganglia runs off of a heartbeat on the client nodes and so if they went into a power save state they would probably show as down. Outside query would probably wake them up though...
Might check and see if those BIOS are set the same as the others (or if there is a related bug). Could explain why just some of them are doing it too (especially if the nodes were purchased in phases). Just a thought, probably a silly one.
