IBaseMessage.Context getting disposed for large message processing (There was a failure executing the receive pipeline: Reason: Cannot access a disposed object. Object name: 'MessageContext'.

Question

Hi,
I am trying to parse a large message (2.7 MB file) in a custom Flat file Disassembler (inherited from the Microsoft.BizTalk.Component.FFDasmComp) this does exactly the same work for FFDasmComp but also promotes the count of disassembled messsages. This
works fine for small messages but for large messages I get this error
There was a failure executing the receive pipeline: "<pipeline name>, <Pipeline assembly>" Source: "Custom FlatFile Disassembler" Receive Port: "ReceivePort7" URI: "<the input file location>" Reason: Cannot access a disposed object.
Object name: 'MessageContext'.
In the event log
what I am doing inside the custom flat file assembly is, I am saving all the disassembled messages in a List<IBaseMessage> and then finally when GetNext() method returns null I am promoting the nRecordCount in the messageContext of all the disassembled
messages. This is where I get the error when trying to promote to the message context.(Cannot access a disposed object, Object name: 'MessageContext'). I think the messagecontext is getting disposed, but it should not as I still hold its reference in
the List<IBaseMEssage);
private long nRecordCount = 0;
private List<IBaseMessage> oDisassembledMessages = new List<IBaseMessage>();
Any idea why this happens ?
Thanks in advance, PLEASE HELP
Surya

Hi Surya,
Are you still facing this issue? and are you using Flat File Disassembler in your Receive pipeline?
If yes then set 'RecoverableInterchangeProcessing' to True.
Please have a look in below articles-
BizTalk
Pipeline - Flat File Disassembler Cannot Access a Disposed Object 'DataReader'

This issue can also occur if you are using Large Size message, in this case you will have to optimize your code.
Thanks,
