                 URL: https://issues.apache.org/jira/browse/LOG4J2-1754
             Project: Log4j 2
          Issue Type: Question
          Components: Appenders
    Affects Versions: 2.6.2, 2.5
         Environment: IBM Websphere, 
java-1.8.0-ibm-1.8.0.3.20-1,

When I am testing my logs in IBM server with websphere 8, I see multiple log files created at the same time, I don't know what's the logic behind it. My logrotate config is for 100MB upto 10 files.

My config is 

{
  "configuration": {
    "name": "logggg",
    "appenders": {
      "RollingFile": {
        "name": "rollingFile",
        "fileName": "/var/log/app/test_logging.log",
        "filePattern": "/var/log/app/test_logging-%d{MM-dd-yy-HH-mm-ss}-%i.log.gz",
        "JSONLayout": {
          "complete": false,
          "compact": true,
          "eventEol": true
        },
        "SizeBasedTriggeringPolicy": {
          "size": "100 MB"
        },
        "DefaultRolloverStrategy": {
          "max": "10"
        }
      }
    },
    "loggers": {
      "root": {
        "level": "DEBUG",
        "appender-ref": {
          "ref": "rollingFile"
        }
      }
    }
  }
}

I haven't seen this problem in Tomcat server on Linux server.

Example, there's test_logging.10 and test_logging.log less than 100M

$ cat test_cor/logging12.log | wc -l
3161

$cat test_logging12.log.1 | wc -l
14

$ cat test_logging12.log.6 | wc -l
14

After 10 mins, I see it only appending to the test_logging.log.
