i'm receving the below error message on memory limit although there is enough default memory limit set on the resource pool and explan plan only shows 288 MB out of 18 nodes cluster which leads to 5184 MB of total memory consumption

What's the MEM_LIMIT set for this query? Have you tried to increase the limit for this session to see if it helps?

SET MEM_LIMIT=100g;

for example.

@alexmc6 I think there's (understandably) some misunderstanding of what the different mechanisms there do. 


Memory estimates only play a role if you set "Max Memory" and leave "Default Query Memory Limit" unset or set to 0. I always recommend against that mode for exactly the reason you mentioned.

Can we set 100g? Or maybe 1000g?
