WriteRegister error and extremely slow export

[scottivers]

I am experiencing very slow export times for certain projects. I cant seem to find any common cause of the problem because I can often export files on what find to be a typical timeframe.

A recent 20-minute project took over 2 hours to create a ProRes 422 HQ file on export, which is my project's Preferred Format. I have a few batch effects but it's mostly timeline color warper applied. Every clip has an effect and the whole sequence is rendered to my local Autodesk Media Storage system before I export.

I could open a different project and export 40, 30-second files in the same format and it'd be finished in under 10 minutes.

So if I export the long export sequence, I noticed in my Console log this:

This was after a fresh reboot of the system. I killed the export process and wrote this post.

Anyone have any ideas? A process with this name having an error seems like there's a strong connection.
