Which logs are you interested about, it is the first time I'm seriously troubleshooting DRBD problem.
The /var/log/messages. just stops having messages on the time of the freeze (see snippet below). is there some debug level I can increase for DRBD?

The problem happens on the "production lan" as well on a 4 port "1Gig staging switch". iperf shows in all cases normal values.
The problems happens on Fujitsu Siemens server RX200/RX300. The total of Fujistu Siemens Servers having this problem is 6 in total. Other servers I have installed do not have this problem. The Fujistu Siemens server have onboard Broadcom interfaces "NIC: NetXtreme II BCM5708 Gigabit Ethernet".

The same seems to happen with 8.3.3RC2. although the error is either to
freeze the system or the system disconnects all network interfaces.
Anybody?

I have a problem when full syncing with drbd the target machine
freezes. scenario is simple whenever a full sync is made manual or
automaticly the syncing is stalled after some time. after the syncing
reaches the stalled states a view moments later the target machine
