Server.log and access file previous record are overwrite

Hi,

I am having problem that my server.log and access file in all instance have been overwrite by latest record. Suppose all the system.out.print will append to the server.log. However, my problem is the log which has been written to server.log in earlier time (mayb morning till afternoon) is replaced. From the server.log, I am only able to view the log which start from 11 pm. The same case happen to access file as well. This incident is not happen everyday but sometimes.

I am wondering what is happen and how i can solve the problem.

Any help/guidance is highly appreaciate.

Thanks.
