Well, I guess there was no continuation so far. On the 9.2-system under question, I changed the backup/snapshot scheme to use the dates in the names instead of doing logrotate stuff (using sysutils/zfs-periodic instead of sysutils/freebsd-snapshot) to circumvent the issue.

I have the feeling that the issue depends on wether the snapshot was used before, is still mounted or something like that. I think when I had just the snapshots running (without the backup jobs), I did not see this (but I may be wrong with this). MM> As for 9.1, I never had this problem in 9.1.
