Strange Number format exception

[Brandon Cruz]

A couple people have posted about this strange exception, but it has never
been answered.  Does anyone know what causes this exception below?  This is
being thrown every couple minutes, even when there is no access to the site.

2001-08-27 02:04:14 - ContextManager: Error reading request, ignored -
java.lang
.NumberFormatException: 3379


Any info would be appreciated!
