> Admission control rejected a query with the following error:
> {noformat}
> ERROR: Rejected query from pool root.default: request memory needed 50.00 GB is greater than memory available for admission 45.36 GB of coordinator-0:22050.
> {noformat}
> The query profile shows the following resource estimates:
> {noformat}
> Per-Host Resource Estimates: Memory=303.36GB
> Dedicated Coordinator Resource Estimate: Memory=136MB
> {noformat}
> The max query memory limit for the pool was configured as 50 GB.
> Based on the coordinator resource estimate of 136 MB the query should have easily fit in the available coordinator memory.  [~tarmstrong] speculated that we might simply be comparing the wrong resource estimate to the coordinator limit.
