FreeBSD 7.0 and Samba 3.3.2 crash over ZFS share

[Alex]

Hi,
I have small home file server running FreeBSD 7.0 and 4x500 GBytes ZFS 
volume. Currently I have Samba 3.0.34 from ports working fine. When I 
install latest Samba 3.3.2 from ports any access to shares residing on 
ZFS volume cause panic in samba. Access to UFS share is fine.
Any body see same problem?
Is it possible to fix?

uname -a
FreeBSD 7.0-RELEASE-p11 #25: Fri Mar 27 19:13:25 EDT 2009     
root at storage:/usr/obj/usr/src/sys/VIAC7  i386

Thank you,
Alex
