ad_read_rsrc_adouble: invalid AppleDouble resource crashes samba - TrueNAS 12 U1

Hey,

We've been having issues with SMB crashing on os on both TrueNAS 12 and U1. The logs before the crash are

It seems to happen either when we're using Adobe Photoshop or Premiere while editing directly off the server with MacOS Big Sur (Ver 11.1 - 20C69), both macbooks and mac pro's, on both wifi and wired connection. I can't attach the smbd.core dumb to this issue, as it is 200MB in size. I can upload it to an alternative location if needed.

smb config is

[global]
aio max threads = 2
bind interfaces only = Yes
disable spoolss = Yes
dns proxy = No
enable web service discovery = Yes
kernel change notify = No
load printers = No
logging = file
max log size = 51200
netbios aliases = server
nsupdate command = /usr/local/bin/samba-nsupdate -g
registry shares = Yes
restrict anonymous = 2
server role = standalone server
server string = TrueNAS server
unix extensions = No
idmap config *: range = 90000001-100000000
fruit:nfs_aces = No
idmap config * : backend = tdb
directory name cache size = 0
dos filemode = Yes

[share]
ea support = No
kernel share modes = No
path = /mnt/pool1/dataset1
posix locking = No
read only = No
vfs objects = aio_fbsd fruit streams_xattr shadow_copy_zfs ixnas
fruit:resource = stream
fruit:metadata = stream
nfs4:chown = true

I feel like this is not expected behavior, as some older forum posts have mentioned appledouble file modifications/creations should be handled by the fruit vfs and I also haven't found an existing issue for this. Hope the issue description is detailed enough, but I will provide more logs/configs upon request!

Thanks in advance for looking into it!
