Only 2 nodes rendering

[mmck]

We have the following licenses on our server:

1x V-RAY FOR SKETCHUP 3.0
6x V-RAY RENDER NODE 3.0

1x V-RAY NEXT FOR SKETCHUP
6x V-RAY NEXT RENDER NODE

We were having issues with only 1 render node showing so I removed Swarm from all computers.

I then re-installed the latest version of V-Ray to 4 Windows machines and 1 Mac, including re-installing Swarm to the 4 Windows computers.

I also updated the license server to the latest version.

The 4 render nodes now correctly list, however when rendering only two nodes at a time.

If mid render I disable one node, of of the other nodes then starts rendering, and if I disable another node the other starts too. Thereby confirming all 4 are connecting properly, but for some reason we can only get 2 running at a time.

There is no consistency or pattern to which 2 nodes are utilised first either. The same behaviour happens whether running from the WIndows or Mac computers.

All 4 Windows computers are identical in hardware specification.

Any thoughts what may be causing this behaviour?

This was seemingly being limited by the available resources slider being set at 50%. We had always understood this controlled the resources on the nodes being used, rather than number of nodes. Seems an odd/duplication of "control" the way it is configured as the nodes can be controlled by tags already.

That's rather 2 different approaches - you can submit to all machines and use the slider to adjust the percentage of machines to be used or you can set the slider to 100% and use tags to add / remove machines.
