client request from the server is delay

delay when receiving client request.

Hi,

I have an Auction portal website, it is now running for a couple of months now.
But I have this problem where sometimes user bid at 00:00:01 second but nothing happens.

I checked my logs, I put it at the entry point of my source code where I need to process the bid request, so I will know if the user was able to bid before the auction closed.

user  time bid was received   auction closed
A     2012-07-11 23:56:31     2012-07-11 23:56:30
B     2012-07-11 23:56:32     2012-07-11 23:56:30

as you can see the auction is already closed after the system received the request.

This happens only once or twice a day, and when this happen at a random time, all bids request are delayed. Also take note that I have a condition that when the auction is already closed, no one can bid anymore, so I am sure that the bid is valid.

I am using PHP (codeigniter) and Mysql. We are using Windows for our server. I am not familiar with our server specs, but I am sure that it is high enough to process everything.

Does anyone of you know what can trigger this delay?

Thanks in advance!
