I suddenly see errors like `Failed to copy child node outputs from [.../outputs.pb] to [.../outputs.pb]`  This happened after upgrading our cluster to 1.15. What could cause this issue?

Do you have any simple example that we can reproduce 

The Github issue I linked above contains an example

this is an issue, and we are working on a fix, you should revert to the previous version for now
