I think the chalk app was trying to report that the phone was out of disk space.
The message was cut off at the end of the chalk session. Just reporting some small issues to help improve the app.
Thanks, @JeffWehrman .
I'll get this back to the dev team. Can you share the device, OS, & version of Chalk you were using?
