Pogman told me he is working on shrinking DB. So, this is just for documenting the exeption

Your Environment

• Uploader Version Number: 0.6.1
• Your Android Phone Model Name (e.g. Samsung J1 Ace): Samasung S4 - CM 13
• Android Version Number (e.g. use 4.4 for 4.4.4): 6.0.1
• Network Connection at the time the issue occurred (Wi-Fi, Mobile): Wifi
• (if relevant) Nightscout website version (e.g. 0.8.4 Funnel cake, master / dev branch):

Yep, the Realm DB can get really big and actually just full of fragmented empty space.

Compacting has been added for v0.7.0 and this reduces the file sizes by a a massive amount.

[verunightscout]

Any ETA for 0.7.0 release ?

[Pogman]

Things are slow dev-wise with the summer so probably autumn sometime.

If this issue is affecting you then clear the app data, you will need to re-enter your settings.

Is there a workround to fix this problem? My tablet was running for a long time without issues. The app is now unstable...

[Pogman]

Workaround is in the previous post.

Closed - completed and available in 0.7.0 release
