Error in SSH2DataBuffer, corrupt string on read


KIE EDI-Services

Recommended Posts

Hello All,

We are currently using 1 VAN to connect via Business Connect SSHFTP and get the Data from the server location. Now we are adding another VAN to establish connection and get the files from server location. We have got the IP and Port open and are able to connect via SSHFTP without any issue using BC. We have connected the BC to check for every 1 min for files and if files exists they will be fetched into our system. But we are facing 1 peculier issue. Sometimes we are getting the "Ssh transport disconnected due to fatal errors: I/O error - read failed" error randomly while we are connecting to the new VAN Location. And this is happening randomly even though there are no files in mentioned VAN Location for pickup. We are almost getting this error 10 to 15 times per day eventhough our system is checking for every minute through out the day.

Log is given below
