Access log messages are stored in a buffer. The buffer is flushed to the access log at the following times:
When the buffer is full
When the access log is rotated
When Directory Proxy Server is stopped
If a buffer is flushed because it is full, the last message in the access log file might not be complete. The remainder of the message is then delivered in the next flush. By default, the size of the buffer is 10 KBytes. However, the size of the buffer can be configured to control the frequency with which it is flushed. For performance reasons, the buffer size should not be reduced to less than 5 KBytes.
You can configure the size of the access log buffer by setting the log-buffer-size property. For information about how to configure access log properties, see Configuring Directory Proxy Server Logs in Sun Java System Directory Server Enterprise Edition 6.1 Administration Guide.
