I just found this post:  
[https://discourse.nodered.org/t/persistent-context-storage/37858/2](https://discourse.nodered.org/t/error-circular-where-is-this-coming-from/7114)

by setting

```auto
contextStorage: {
        default: {
        module: 'memory'
        },
        disk: {
           module: 'localfilesystem', config: {flushInterval: '600'},
          },
     },

```

I can keep it all in memory, but flush to disk at the end of every cycle with:

```auto
flow.set("my_object", content, "disk")

```

That will do the trick
