I have one app running in an old server Solaris 10. In this server, after migrate log4j1 to log4j2 we start to get an error while start the app.

In this app we set the logger properties using the java arguments
log4j2.configurationFile="cfg/logger.properties"
as we can see in the firsts lines of the log, the configuration file was loaded correctly.
Running in a linux server, our development machine, this error not ocour, and the log files is like this:

I already check the java, ant and libs versions, but I can't find any significant diference that can impact my application.
I need ideas of what I can tray to solve this issue...
