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 thousand= s 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. --=20 With respect, Roman --Sig_/YNG.=450.D0gH.gWStz3R6+ Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlODbjQACgkQTLKSvz+PZwgMlgCfWOT+96tabQUeJWjgdVbjv3xR jOYAmwa9Mf0r6y8mgbMN64TzYERnZirM =Q9CP -----END PGP SIGNATURE----- --Sig_/YNG.=450.D0gH.gWStz3R6+--
