The /usr partition constitutes the bulk of it. The volume is sitting around 95% full, and twice I've had the system become "hung" in what I believe are filesystem operations. It seems to crop up when rtorrent tries to create files that would fill up the system, but of course it doesn't actually reserve it until it is used. Any running process remains responsive until it needs to access the disk. The system was running a fairly recent 6.2-stable, March 29, but I've since updated to the most recent -stable. If anyone can give me some pointers as to how to tell exactly where these processes are hanging, I can try to reproduce it... But it takes a while to fsck the volume so I don't want to have to try too many things. If it's not a known problem I can then submit a PR. Thanks! -- This .signature sanitized for your protection
