SFTP Subscription Error

  • For SFTP, we have tested the Reports with high data volume by creating more than 50 subsriptions. But 50 % of the reports ended up with failure after encountering the message ""Cannot access a disposed object. Object name: 'System.Net.Sockets.NetworkStream'.".

    Kindly Guide us In Investigating this matter further...

  • I'm looking at a similar issue as well but we're using a custom sFTP extension that adds sFTP as an option to subscriptions. Right now we're looking at the network. I've done some Netmon traces on the source SSRS server but that hasn't yielded much. I don't have access to the destination sFTP server to perform a Netmon but our Network team intends to use a network sniff to perhaps capture what's happening cause from the Netmon I'm not seeing anything coming back.

    This is a snippet of what I'm seeing in the Netmon but that's it.

    Source Destination TCP 4372 > ftp [SYN] Seq=0 Len=0 MSS=1460

    Source Destination TCP 4372 > ftp [ACK] Seq=1 Win=65535 LEN=0

    Source Destination FTP Request: USER anonymous

    Source Destination FTP Request: PASS somebody@somecompany.com

    Source Destination TCP 4372 > ftp [FIN, ACK] Seq=48 Ack=131

    Win=65404 Len=0

    Source Destination TCP 4372 > ftp [ACK] Seq=49 Ack=132 Win=65404

    Len=0

    Not sure if yet if it's something in the code for the custom extension or something in the environment yet. I'll try to let you know what I happen to find out.
