HA OS, release memory of emmc after faulty template

Hey Guys,

I have the following problem:

After a new installation, I had a memory consumption of about 8% (64 GB emmc) on my odroid m2+. I then entered something wrong in a mushroom template, which caused thousands of errors to be thrown in the log. By the time I noticed this, I had already transferred the error to a few other cards. By the time I had deleted them all, my memory consumption had risen to around 15% within minutes, where it has currently been for a few weeks.

Now the question how do I get the memory free again? Purging the database was unsuccessful.

Any ideas?

Thanks very much.
