Q: 

Control process concurrency in PHP

I have programmed a simple app that every X minutes checks if an image has changed in several websites and downloads it. It's very simple: downloads image header, make some CRC checks, downloads the file, stores in a MySQL database some data about each image and process next item...

This process takes about 1 minute to complete.

The problem is I have noticed that while the server is executing this process I cannot access to any page in the website, even those that don't require MySQL.

I don't know why it is happening and I have no clue about how to fix it. Perhaps a more advanced PHP programmer can help me.
