Embedded data collector down (Chargeback 2.5.1)

Hi,

recently the System Health tab show that DataCollector-Embedded (Host: XYZ) is down. Strangely the issue occours since a few weeks.

This resolution (VMware KB: vCenter Chargeback Manager 2.5 Patch 01 ) doesn't work so I've setup a clean reinstallation of vCenter Chargeback Manager v2.5.1 (before and without patch: 2.5.0).

After the reinstallation the status of the data collector shows "UP". YEAHHH!!

But... a few minutes later the status is "DOWN" again.

I've no idea what i can do to solve this problem. Anyone an idea?

Regards
