Seeburger sFTP receiver adapter error: Socket Write Error, EOF Received

[minal_vaidya2]

Hello experts,

We have a sFTP to sFTP scenario for which we are getting below error every time the scenario is executed.

Error Messages are as follows:

Put File: Could not connect to remote host, Reason: Unexpected termination; software caused connection abort; socket write error[unknown cause].

Sometimes below error occurs :

Put File: Could not connect to remote host, Reason: EOF received from remote side [unknown cause].

Every time after restart of sFTP adapter on XI box, failed messages are sent successfully to receiver sFTP server.

There is no error for sender sFTP channel. This error occurs only for the receiver sFTP channel.

On receiver sFTP side, we are using Public key-private key authentication.

Can anyone please let me know what could be the cause of connection failure. ?

Thanks a lot in advance!

(I searched many threads on SDN but could not find anything relevant to this particular situation, so posting a separate question.)

Hi MInal,

Cross check if your keys are properly exchanged.refer below link for reference.

Thanks Naveen for the reply..

I missed to mention that we are working on XI3.0 with SP19 and seeburger sFTP is 1.7.4

Looks like key exchange is working properly as after every restart of adapter all failed messages are processed successfully..

It is observed that if there is an idle time of 8-10 hours between last data transfer and current data transfer then this error occurs.

We have increased connection timeout and transmission timeout parameters also for sFTP properties in visual admin.

Thanks,

Minal

It was a bug in Seeburger sFTP, and we had to upgrade it to next version.
