That's an interesting point. I've been cautious about enabling skinny extents as well, and haven't enabled them here. (Nothing major, just a couple early reports that I expect have long been worked out by now, but I decided giving them a few more kernel releases to mature was probably a good idea.) So it'd be interesting to see if there's a correlation between skinny extents and the memory issues as well, as there seems to be between qgroups and the memory issues. -- Duncan - List replies preferred.
