>Description:
Hi - I took a snapshot of /var, and mounted it.  I then started a copy to /var, and took snapshots while the copy was in progress.  Once the partition was over 85% full, I stopped taking snapshots.  4 snapshots were takin of /var.  When the partition became full, the kernel paniced with:
ffs_copyonwrite: recursive call
>How-To-Repeat:
Take a snapshot, mount snapshot, fill FS on which the snapshot was taken.  While copy is in progress, take a couple more snapshots.  I'm not sure if that is necessary.
