Too large file called "on" in nginx installation folder on windows

[mpunaskar]

Im using Nginx Version : 0.8.54 running on Windows 2003. Its being used
to server large number of static files with filesize varying from 10 kb
to couple of mb in size.

Nginx creates file called "on" in installation folder which keeps on
growing. 

Can any one guide me as to what this file is and how can i stop/manage
its size growth?

Thanks,

Mandar
