I have a pivotal tc server SE running. There is a springboot web app deployed with log4j2 logging framework configured. The log4j2 properties has console and file logging enabled with TimeBasedTriggeringPolicy enabled which creates new file every day with the date appended to the previous date. The logging seemed to be working fine until recently where the server was taken down for maintenance.
Issue: The logs are not being written to custom file(File logging) anymore after the server startup. I can still see console logging happen. Re-deploy isn't fixing the problem too.
Note: The server shutdown and startup was done on different days. Not sure if this information matters.
Log4j2 startup logs when Configuration status = debug
