If I change the logging configuration (standalone/configuration/logging.properties) as the following to prevent console logging:

#logger.handlers=FILE,CONSOLE
logger.handlers=FILE

Server does not start. The log file (standalone/log/boot.log) seems broken and sometimes OutOfMemoryError is recorded:
