@silverpill Ah right.. in that case, nothing unusual in the logs that I've seen yet. My experience of Federation getting "stuck" is only anecdotal, maybe I'm just perceiving things that way. If I happens again I'll make sure to check stdout before restarting anything.
In terms of the media folder, it's gotten up to about 8.9Gb now. I feel like the growth is slowing down, but if it gets too close to 3/4 full I might change the pruning job to 15 days old instead of 30, see if that improves matters. I figure two weeks of post history is more than enough.
