Yes, the Sun GEM interface is the problem. Ethernet over FireWire (a direct link between the webserver and database server) works just fine. In a minimal config with no devices enabled except the SU serial line (needed for console), the dual SCSI adapter and the Sun GEM nic, the problem still remained the same.
