Webservice shut down

Hi @donisback, welcome to the Render community!

It sounds like some other users have run into a similar error before. You may want to look into increasing the value for --max-old-space-size. Some helpful links around this here: Node crashes periodically - #2 by shantanu
You may also want to try temporarily increasing the plan for your service, increasing the memory to see if that has any effect - you can always downgrade later if needed.
