Strange error?!

[=?Utf-8?B?RGVhbiBHYXJyZXR0?=]

We have a .NET app that selects records from a SQL Server 2000 database, and
then sends out e-mails using the System.Web.Mail class in .net

This has worked for months, and then suddently, the runtime error below
starts happening. If we select a small number of records, everything is fine,
but if we select say 1,000 records then this error occurs each time.

I can't find any information about this error message. Could it be due to
something in a recent Windows Update? It is running on a Windows Server 2003
server.

Thank you for any hints!

Hello Dean,

DGSystem.Diagnostics.EventLog.WriteEntry(String
DGmessage, EventLogEntryType type) at

relating the error stack you are writing to the even log and got Win32Exception.
Are you sure that the source, where are you writing the log, exists?
