Hey @caiquezanetoni
This doesn't look like a bug, it just looks like you don't have enough memory on your machine for n8n to run what you are putting through it.
What are your workflows doing and what sort of resources do you have available for n8n?
How do you have n8n deployed as well?

Hey @caiquezanetoni,
The error message means NodeJS doesn't have enough memory, You can try and allocate more memory by setting NODE_OPTIONS=--max_old_space_size=4096 but I would recommend tweaking the workflows first.
As this doesn't appear to be a bug with n8n itself I am going to mark this as closed, Let me know how you get on with increasing the memory available or if you have any other questions on this.

@Joffcom What do you mean by that this is not a bug with n8n itself? Isn't n8n capable of running within the constraints of memory, say, for example, by offloading data to disk to free up memory?
