<br>
Thanks for the quick answer.<br>
<br>
Yeah, I figured it would be slow. That's why im trying to cascade it<br>
instead of having 2000 subvolumes directly attached to the top node :)<br>
<br>
Anyway, I'll have a go at the 1.4.0.rc2 version in the meantime and let<br>
you know if it also crashes.<br>
<br>
Cheers,<br>
