Unity - Unisphere CLI - real time metrics maximum number of queries... can't query anything.

I keep hitting a wall with real-time performance metrics via Unisphere CLI on my EMC Unity device.

The query I am attempting to do is similar to that found in the Performance Metrics docs ( https://www.emc.com/collateral/white-papers/h15161-emc-unity-performace-metrics.pdf )

I am trying to do the following:

uemcli -u 'myUserName' -p 'mypassword123' -d 'myIP' /metrics/value/rt -path spa.*.storage.lun.*.writesRate show -interval 5

Operation failed. Error code: 0x7d1400e

Unable to create any more queries. The system has reached the maximum number of active queries [5]. (error code:0x7d1400e)

I am still able to get my historical metrics, but NOTHING real time works.

Any input on this would be greatly appreciated.
