As i know, we didn't use NAT or a FW between the clients and the AFS-Servers.
I found the potential issue, i think.
The UUID for the client (cache manager) isn't calculated:
'cmdebug <client> -addr' shows:
UUID: 00000000-0000-0000-00-00-000000000000
Host interfaces:
Capabilities:
Error Translation
The clients have a bonding of two interfaces:

Is this the problem?
How is the UUID calculated?
thanks and best regards
