Messaging instance stays active

Mar 24, 2010 at 9:27 AM


we use sftp adapter in a send port, sending files to remote sftp server, with temp file name and temp folder.

With small files, everything works great, but with big files (~700 Mb), messaging instance stays active in BizTalk MessageBox, with no message in it.

Actually the message is transferred and renamed as expected, but messaging instance doesn't stop.

Is it a known bug, or resolved in latest version?

Thanks for your help,

This is strange, and I've never seen it before, but then I don't usually work with 700Mb files ;)

The weird thing is that the message get transmitted. I think you need to debug it in order to see what happeneds. I'd sugest you start looking at the ProcessMessage method in the SftpTransmitterEndpoint clasee ( \Blogical.Shared.Adapters.Sftp\SftpTransmitterEndpoint.cs)

What  version are you running now?

Thanks Mikael,


I'll try to debug asap, but I'm busy on other projects right now. As I said, transmission works, bur remaining empty running instances make production guys not very happy...

We run the 1.3.4 version on a BT2006 R2 sp1.

I understand the concern. Let me know. If you're in a hurry contact me through my blog (mail or IM)

Hello Mikael,

We found out the instance stays active because we chose "Ordered delivery" on the "Transport Advanced Options" tab of the SFTP Sendport.

Kind regards,
