Now I see the following:
The node had restarted.
GC has appeard to resume, meaning that it created a new trash date folder with current name.
But when I look now there is only a single subfolder in it (the one that should be resumed with) and nothing else. And all stored bloomfilter files from the retain folder have vanished. This means that the bloomfilter for the US-1 satellite has vanished which was under processing before node restart as well as the 2 bloomfilters from EU-1 satellite are now gone.
