samba crashes when streaming files to VLC, bad file descriptor

When I stream video files from Samba to Windows using VLC, samba streams the first few seconds of the video then crashes. VLC shows a "bad file descriptor" error. I've been using the same configuration for over a year with no problems and can't think of any recent changes that could cause this. Samba has no problem copying files.

I've tried uninstalling and reinstalling samba, using the stream from a separate windows machine, and streaming from MPC instead of VLC.

Ubuntu 14.04.4 LTS
Samba version 4.3.8-Ubuntu

The log seems to show that it repeatedly goes into panic when I start a stream.
