Greenplum ERROR: Canceling query because of high VMEM usage
From ERROR: Canceling query because of high VMEM usage on the vmware Tanzu Community by Faisal Ali:

&quot;Canceling query because of high VMEM usage&quot; is when the segments uses 90% ( default ) of the gp_vmem_protect_limit. If it's the same query with the same error all the time, it would be better to check how much memory is the query using and take a explain plan to understand the query execution path and fine tune the query.
