Inputs on the apache logs

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
Can you explain me in brief of how the apache logs gets written.Does it have any buffer mechanism while writing it into the file?I am sing Apache 2.2 with Worker model.When my webserver is overloaded i don't see my access logs file growing for at least 1 min and again later on it grows.Later when I check the entry in the access log I do see entry of the logs during the time when the logs file size was not growing.
Thanks in advance.
