Indexing not running on Management Server

In my Acronis environment I have three Acronis boxes that handle the backups. The first system is a Dell 1950 with 16GB RAM etc.. This one is our Management Server / Storage Node. A second Dell 1950 with the same spec is a Storage Node. A third system (i7/12GB RAM) is also a Storage node. All three systems point to vaults we've created on our Netapp over our 1GB SAN. All tree vaults are configured the same as Managed, Dedupe on, Compression on, Encryption off. Oh, the Database is stored locally on the servers secondary drives.

When the backups run I see Indexing tasks run for each backup process but only on the dedicated storage nodes. I've never seen it run on the Management Server that is also a Storage Node.

Currently we have our systems divided between the three servers with about 17 PCs per node.

When I attempt to run the indexing task manually I get the following error...

Can anyone tell me if this is normal behavior or do I have a problem to address?
