Crash with filled up /cache/
**Describe The Problem:**
Homebridge is randomly crashing and doesn't start up again before I clear /cache/ folder.
Sometimes it takes the whole raspi down.

**To Reproduce:**
It's kinda hard to reproduce because it's happening randomly

**Logs:**
I cannot send a log due toe homebridge only keeping 2 days of logs. As soon as the failure occurs, I'm going to send in the whole log. I'm adding the log anyways, reduced by temperature changes..
