Hi Im having problems runing a forecast, when I use the kibana GUI it throws me a Bad Request error and when I use devtools I get this error.

`Cannot run forecast: Forecast cannot be executed as forecast memory usage is predicted to exceed 20MB while disk space is exceeded`

Searching in the documentation there is an optional parameter `max_model_memory` but this parameter doesnt exist in my version of elastic 7.8.

what can I do to solve the problem? other than add more nodes...

7.8 is [EOL](https://www.elastic.co/support/eol) and no longer supported, you should really upgrade 🙂

Chances are there are improvements to help with this, and you can get access to `max_model_memory` as well.

Hi, -thanks Mark, Sadly I can´t upgrade right now, any other thing that you may think to solve this?  
less jobs on the node?  
filter the datafeed?
