Question:
What does it mean when a two-digit number occurs after the date and time stamp in a WP log and WP forced traced file?

WP log:
two-digit WP log

WP forced trace file:
two-digit WP forced trace
Environment:
Linux
Oracle Database
Answer:
The two-digit number after the date and time stamp means the Automation Engine was unable to connect to the Database.

This can be seen in the WP log:

This is normally where the Database information gets written in the logs when connection is successful. When unsuccessful, then it gets replaced by this instead. 

The WP forced trace file confirms the Database issue:
