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

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.

Would you like to share more inputs by looking at these logs?

In my opinion there is a general issue with the connection to the backend which is not reachable for unknown reason or where the client request URL is not correct and can't find the resources.
A 500 error might be caused by a backend refusing connections or a "man-in-the-middle" which is preventing the traffic to go through.
Did you track the connection with wireshark and/or Fiddler?

Andreas
I find the error "Response code from backend is 500 for request null" interesting. I would try and trace that communication to see what is being issued to backend server.
Also:
10:25:32#+00#ERROR#com.sap.mobile.platform.server.mobilink.SessionLogger##<<user>>#Thread-161##c4d6cf51-44cf-4f10-af0c-4481eb6dfabe#<<appid2>>#626e3c81-406e-11e5-8000-ea606b473f19#RequestResponse#404##[-100027] An error occurred while processing request "Cities" (https://server:port/....//Cities?$top=50)
There is either a bad request going to backend or backend is having issues.
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.

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.

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.
