达到了wrapper.logfile.maxsize

The wrapper.log file can be set to roll when the file reaches a specified size. The default value of 0 will disable log file rolling. To roll the file,specify a maximum file size in bytes. The size can be abbreviated with the suffixes ‘k’ for kilobytes,or ‘m’ for megabytes. For example,’10m’ sets the log file to be rolled when it reaches a size of 10 megabytes.

或其中一个条件

满足wrapper.logfile.rollmode

Controls the roll mode of the log file. Possible values include:

JVM – The log file will be rolled on Wrapper startup as with the WRAPPER mode. But it will also be rolled just before any restarted JVMs are launced. The log files will not have a maximum size and will continue to grow until the Wrapper or a JVM is restarted.

DATE – As each log entry is logged to a file,its timestamp is compared with a YYYYMMDD formatted token in the current log file. Whenever this date changes a new log file will be opened. This has the benefit of grouping all log entries for a given day in a specific file. A file will not be created on days which do not have any log output.
