ECC 6.1 / Vm ESX Discovery Error in EGV_Err.log

Hello,

i am trying to discover ESX Hosts over VirtualCenter Host or direcly.
The VM Agent is running on the CC Server itself.
I do get the message:
EGV 12:55:16 EGV 1 P E 4892 (11.02 MB) EGVAgent::RunDiscovery => Failed to send the VMware data to
- store for: "Hostname"

Within the logfile EGV.log the discovery is succeded.

Within teh ECC Console i just the the manual created Hosts with HBA info. No ESX Tab or VM information.

Any suggestions ?

Thanks in advance
