If i get it right after 10mb of log files, the log files will start
getting overwritten?

If that is the case, just a curious thought, 
we will start loosing the logs if the entries not happen in 10MB.
Say customer is doing high activities that lead to log full quickly,
then we might loose the debug log that might have useful data.

Can we have something like once these 10 files are written, zip them and
create a tar files say log1.tar till log5.tar. Which means we will have
10MB * 5 =50mb of log files.

We had this experience in AIX, and we were forced to store more debug
data.
