Intermittent IndexOutOfRangeException: Index was outside the bounds of the array

[scotthutchinson]

I have a .NET Remoting object hosted in IIS6 on Windows Server 2003
(happens before and after installing SP1) at an endpoint (ASP.NET
application virtual folder) named "CompanyXYZReporting". The remoted
object is called several times every day and works perfectly except
every 2-3 weeks when we call the remoted object, the response returns
the error shown below. Does anyone have any clues how to resolve this
problem?

Server Error in '/CompanyXYZReporting' Application.
