Error: Could not send cancel request: PQcancel() -- connect() failed: No buffer space available

Good morning,

Sometime when I try to cancel a running query in vsql, I get the following message:

Could not send cancel request: PQcancel() -- connect() failed: No buffer space available

Note, the query does cancel, but what does this error mean?

I suspect your workload may be far exceeding your available hardware's capability! Did you configure 2 GB of TEMP space for Vertica?
