From what I can tell it has significant improvements/bugfixes in the snapshot deletion area. Just a couple of days ago I got a recurring lock-up after deleting 50 snapshots with tens of thousands of fragments of files in each (VM images, like in your case). Googled around a little bit, and found a similar issue with a report that 3.14 solves the problem. Upgraded to 3.14.4 (from 3.12.20), and voila, indeed it does. -- With respect, Roman
