we have a strange problem with our NW 6.5 SP6 2 - Node Cluster:
every few weeks one server stopps communication with the network.
(both LAN and SAN)
The other Server abends.

- 2 Node Cluster with NW 6.5 SP6
- Netapp as SAN Device (one mirrored LUN)
- 2 Serverrooms with glass fiber connected
- Server: IBM x346
- 3Com Switches with 802.3AD
- 2 x 2 B57 Network cards with 802.3AD LACP Passive
- Heardbeat over LAN
- iSCSI to NetApp
