Memory leak when a reflection creation fails?

Hello,
I am using Dremio 3.2.
When trying to create a reflection on a VDS, I get an error message :
“Query was cancelled because it exceeded the memory limits set by the administrator.”

The problem is, after that, the memory used by one of the node doesn’t come back to its previous level (below 1%) : it stays at 88%, and the service needs to be restarted.

Any idea about what is going on ?
