Understanding Log Error Alert

[NOS]

Hello,

I am using version 1.8.2 on Centos 7 with Docker and I keep getting this error message every 5 minutes and I am trying to understand what it is telling me. All of the current displays that are up and running are doing so without any problems and there aren’t any layouts that have regions that are blank (that I can find). Is there a more concise or deeper meaning that I am missing here?

This is the recurring message:

Every 5 minutes (by default), a background process builds all the layouts in the system that require building. It’s telling you that one or more layouts are invalid because it has an empty region on it.

You should find that layout, and correct the issue.
