log4j2 logs are not writing into log file after initialization of application

Question

I have migrated legacy application log4j version from 1.2.X to 2.17.X version. Below steps I followed in local windows WebLogic server and it works fine loading testlog4j2.xml and writing logs into log file while invocation of application.

When deployed same code on Linux WebLogic hosted test server the log file created during WebLogic server starts later application invocation logs are not rolling into the log file.

Please advise any one faced same situation and how it resolved? Local and Test environment using same version of WebLogic server wls 12.2.1.4

Code Snippet for local(windows) and test environment(Linux):
