I haven't figured out a way to identify the problem, still trying to find a 100% way to reproduce this problem. Seemingly the more snapshots I send at a given time, the likelihood of this happening goes up, but, correlation is not causation :) I might try to open a support case with Sun (have a support contract), but Opensolaris doesn't seem to be well understood by the support folks yet, so not sure how far it will get. -- Brent Jones br...@servuhome.net _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
