[Samba] "stuck" new directories and Mac Finder hangs after upgrade to 4.2.11

[tackyy]

Hi,

I’ve been searching online for a few days and am still hurting for an answer, otherwise I wouldn’t jump into a list and start asking questions straight away.

We’re a 99% Mac shop running El Capitan (10.11.4). We’d been running Samba 4.2.3 on FreeBSD 10.0/ZFS for a while with minimal problems. I recently upgraded to 4.2.11 because of Badlock. Now when users create a new folder then try to move files into it the Finder hangs, the user loses their connection to the server and if you try to ls or rm those directories while shelled in those processes get stuck as D+. I’m not seeing anything in the logs that correlates with when this happens either.

There is no netatalk in our environment if that’s a factor. We don’t have fruit, catia or streams_attr explicitly set in smb4.conf, nor any of the fruit:* settings. Just zfsacl. Is this where I’m going wrong? Would turning those on help?

Cheers,
tack
