Performance issue - logger level reset to lowest

[girardm]

In some circumstances, the level of a logger appears to be reset to 12 (lowest), causing a loss of bxilog performance.
I could not isolate the problem.

Please find attached an excerpt from our code and the resulting trace.

# initialize the global trace variable
logger = logging.getLogger("beo.common")

def configure_logging(argv, args):
    """Configure logging according to general trace options"""
    # general configuration
    config = ConfigObj(CONFIG_BEO).dict()
    log_config = config['logging']
    log_config['history']['file'] = log_config['history']['path']
    if args.verbose:
        deep_update(log_config, config['logging_verbose'])
    elif args.debug:
        deep_update(log_config, config['logging_debug'])
        log_config['debug']['path'] = '/tmp/%s-%d.dbg' % (os.path.basename(argv[0]), os.getpid())
        log_config['debug']['file'] = log_config['debug']['path']
    elif args.quiet:
        deep_update(log_config, config['logging_quiet'])

    logging.cleanup()
    logging.set_config(ConfigObj(log_config))
    # display the selected level
    if args.verbose:
        logger.info("verbose mode activated")
    elif args.debug:
        logger.debug("debug mode activated %s:%s", os.uname()[1], log_config['debug']['file'])
        logger.debug("argv = %s", argv)

    logger.out("1/level=%i",logger.level)
    logger.out("2/level=%i",logger.level)
    logger.out("3/level=%i",logger.level)
