This error message sometimes indicates a communication problem.
(Grrrr, what an obscure message.)
Do you mean 3c509 (ISA) or 3c905 (PCI)?

The slave nodes have a default configuration to reboot if they lose the
connection with the master for 30 seconds. This allows automatic cluster
recovery if something happens to the network connection or master. You
can change the reboot configurable after boot, but you usually would
change the 30 second reboot default only with a multiple-master fail-over
