log4j: what happen when size of log file is close to limit?

Question

Assume that the size limit is 10M and the current size of log is 9M. When I use logger.info() to append a string, with 2M size the log will be renamed log.1 and create a new log file.

I want to know if log4j is about to split such string, how to prevent it from splitting and moving the entire string to the current log file?

Answer 1

Wouldn't be splited, log.1 would be 11M.
