the log is rolled. Size is specified in bytes. The default value

of 0, disables log rolling by size. May abbreviate with the 'k' (kB) or

'm' (mB) suffix. For example: 10m = 10 megabytes.

If wrapper.logfile does not contain the string ROLLNUM it will be automatically added as suffix of the file name

files are deleted. The default value of 0 implies no limit.
