Circle CI Shader error happening sometimes

Hey guys, I'm creating automated builds using Circle CI.

Every so often, maybe like once every 6 or 7 builds I'm running into the issue where this line displays over and over again for about 30 minutes and then the build fails.

I was curious if anyone was familiar with this before? It happens on Android and iOS builds.
