gbde encryption and server crash

[Chris]

Does gbde encryption have known stability problems?

Reason I ask is in the past I remember having numerous problems with
it and tried it again today, within 30 secs of sending a file to the
partition the server died and is offline and I am waiting for it to be
rebooted (remote server)

I followed the handbook to the latter.

I set the sector size to 2048 as the handbook said although the file
says to leave at 512 for best stability.

Freebsd 6.2-STABLE if the box still boots as I am worried it wont then
I will provide a dmesg and kernel config output.
