Ssis Package Hangs On Script Transformation When Running On One Machine Not Developing Machine

Help!
I am using Script Transformation to output a new column as image[DT_IMAGE]
field to store serialized object. In the VB script, the sample code as

Row.serializedobject.AddBlobData ( binaryArrayReturnedFromC#dll )

The package always runs fine on my developing machine and will halt on other
machine at AddBlobData after certain number row records were processed. I am
stuck here. Anyone has any suggestion?

What I need is reading data from mutiple tables in one database and writing
into a single table in another datable. In order preserve all the columns
data, I use input column fields to construct a new object and then serialize
it, and store the serialize data into detination db table. (The object and
serialization function is coming from c# dll.)

Dim b As BusinessLicense = New BusinessLicense()
b.ApprovalDate = Row.approvaldate
b.BusinessId = Row.busid
b.BusinessName = Row.busname
b.NaicsCode = Row.naicscode
b.NaicsDescription = Row.naicsdescr
b.OwnerName = Row.ownername
b.Phone = Row.phone
b.Pkey = Row.pkey
b.RenewalDate = Row.renewaldate
b.StartDate = Row.startdate
b.Suite = Row.suite

Row.serializedobject.AddBlobData(Serializer.Serialize(b)) '''----This is blocking line
Row.infoType = BusinessLicense.TYPE



Both machine is xp with sp2. and standard SQL Server 2005 - 9.00.1399.06

Thanks!
