Error [-10279] Connection was dropped due to lack of network activity

Hello Experts,

We are working on SMP3 OData native apps development, we have been observing mobilink related error entries in SMP server logs. By looking at the logs, its not possible to predict which error entry could be related to which application/user?Can these error be ignored? Is there any solution/best practice to solve it?

SMP3 server: SP08

SMP3 mobile SDK: SP07

Device: Android, Windows, iOS

    Hi JK, Did you explore networkcheck-tool, it should catch these type of errors: http://scn.sap.com/community/mobile/blog/2015/01/06/networkcheck-utility. Unfortunately if they are VMs, rarely happens. Also check event logs for more information.

    Is there any application errors or just these messages?  This could just be a logic issue in client application not ending cleanly and have no real impact.

    Is that an upgraded server from a version prior to 3.0 SP06?
    What is the underlying database? Is it still Derby or SQLA?
    Is it an external database?
    I agree with Kevin that these message might not have any impact.

    Hello Kevin, Andreas

    Thanks for your response.

    Server has been upgraded from SP06 to SP08

    Underlying DB:Oracle (yes external)

    I collected latest logs between two mobilink error messages. These mobilink error message are not specific to particular appid.

    • JK,


      Any luck with this error message? I actually see an intermittent error opening the online store on the client side (it only shows on opening the application post login).
      Once I clear the error message and try again, the online store opens as expected.
