That's a message from the Java garbage collector. You can ignore it. (I am surprised you have MaxTenuringThreshold set. You need to be in a world of hurt regarding GC before you resort to tuning tenuring!)

The message we want would have been in an earlier log. I suggest you follow the [instructions](https://discuss.elastic.co/t/forbidden-12-index-read-only-allow-delete-api/126067/12) for recovering from a disk space issue and see if that resolves this.
