Upgraded to vCenter6. Empty inventory (but tasks, inventory lists etc ok)

[asp24]

I've upgraded from vCenter 5.5U2 to vCenter6. Everything works (including the Windows Client), but in the Web Client I get the message "empty inventory" when clicking on various tabs (datastores, hosts, vcenters, networking etc).

If I click on Inventory Lists I can find most elements. If I click on a datastore there, I can see the VMs running on that datastore etc.

I also see tasks going on in vCenter (migrations etc). I have checked permissions, and all seems OK. I have tried both domain and "SSO" (administrator@vcenter.local) logins, and the problem is the same.

I did the upgrade "offline", where vCenter only had access to the domain controller, in case of a upgrade failure the hosts agent would not be upgraded. All seemed good, so I let that happen. But then I noticed this problem after starting up vCenter connected to the network.

Any idea what could be the problem?

Works now. I increased Inventory Service Java Heap size in "C:\Program Files\VMware\vCenter Server\invsvc\wrapper\conf\wrapper.conf".

I found no wrapper.java.maxmemory line, so I added it (guessed it would work after reading some equal lines in older versions).

I have restarted several times before this without any luck, so I think this was the thing fixing the problem.

I set the max to 2048

I tried changing this in the config-file in this folder first, but that did not help.
