Help on Apache handshake

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
I am using Apache 2.2.8 with MPM=worker under Red-Hat 3.0.
I am having the following issue, under heavy load I observer the access log doesn't grow at all for sometime although the incoming traffic is active. I did a tail on the access but it stopped growing then again after sometime it was growing.This behavior is happening repeatedly with some time gap.

I have disabled the Apache log rotation then also the behavior was same.Any help would be very much appreciated.
Thanks
