Description

There are a number of messages that normally appear on the ELM VM console that are in fact benign and not an indication of any problem. These are messages that Linux outputs internally and not errors or problems reported by the App Layering software. These are normal messages that are produced during file share and layering disk operations. Ignore them.

As shown on the console, these messages are of the form "[seconds since boot] text". The specific content of your messages will differ from these examples because we have removed the timestamp, and there will also be device ID differences.
