hi,
I created a CSV lookup table, with Graylog 2.3.1. I accidentally misspelled the file name. This resulted in error in UI (the triangle), due to missing file. I edited the correct filename in the UI, and the error vanished from the UI. But the java exceptions keep occurring in the log file. So I decided to delete the whole lookup data adapter. The adapter vanished from the UI, but - the java exceptions keep occurring on the log file.
I have a setup of 5 Graylog nodes, and don’t see any problems with their connectivity with each other.

Any idea on how to remove this stuff from mongodb? Or other hints?
