System.IO.IOException: No space left on device... Even though there is enough disk space

[MosquitoCoding]

Hey today I just saw my bot crashed. I tried to restart it but it won't start and keeps crashing on startup.

Log on crash:

I am very sure that I have enough disk space. I checked my whole server size with du -a / and it has not reached its limit by far. I even tested to upload a 500mb file on it with no problems and deleted it and tried to start the bot again. I dont know why but it sais no space left on device

Can you paste the output of df -h please?
It could be another partition that filled up (like /tmp).
