Resolve 15b4: Timeout when waiting for frame

I'm using Resolve 15b4 Studio on a SuperMicro 7048 and rendering stops when I hit an offline clip that's not in the media pool, Resolve hangs and displays "Urgent message: Timeout when waiting for frame 82367 for recording, frame dropped". Only way to fix it is to quit resolve and disable the clip in the edit page.

Using a Linux Advanced dongle trying to render ProRes individual source clips.

I don't recall this happening on previous versions. Otherwise, the Beta rocks. Did you guys also fix the read speed glitch that caused timeouts rendering? This version seems much more stable when network storage encounters some slowdowns.

I can PM a link with the error logs.

System specs:
CentOS 7.4
Supermicro 7048 w/ 3x PNY 1080ti and 2x 2697 v4 cpu
NVIDIA Driver: 390.42
Resolve 15b4

Thanks!
