Hi experts,
I am experiencing an issue that I need to resolve. It is that I lose the connection from SUM GUI (locally) to the SL Controller running on the remote server.
Currently I am doing an upgrade and after some time, e.g. when I have an error and don't notice it immediately, I get a warning message.
"The connection to the SL Controller is down.
The SDT GUI will reestablish the connection, when possible."
On the server I get the following error message:
May 26, 2014 7:49:47 AM [Error]: com.sap.sdt.engine.core.communication.FactoryAlreadyRegisteredException: Factory for key 'com.sap.sdt.engine.core.com

My current assumption is that the firewall drops the connection due to inactivity.
The main issue then is:
although I restart my local SUM GUI and reconnect to the server I can't continue the upgrade because the Buttons are "unclickable" (grey).
Currently I always had to restart SUM including the services on ther server (SL controller).
My question is:
Unfortunately we can't do much about the firewall settings due to security restrictions.
I would be glad to hear from you.
Kind regards,
Niklas
Yesterday had the exact same problem using SUM10SP10_5-20006540.SAR when my VPN connection dropped.
Since I don't have too much time to check the root cause and I got the error at the beginning of the upgrade, I downloaded SUM10SP10_7-20006540.SAR and restarted the upgrade process from scratch.
Hope it was related to patch level 5... although there's no related entry in the changelog...
Regards,
David

Hi Mathias,
I got an answer from SAP. There is no option that can be executed with STARTUP to solve this.
I already proposed to forward this request to the dev team at SAP
What I am currently doing is:
Start the GUI and keep it open only if I know if there is are Actions coming next, otherwise I close it (only the GUI) and when some time has passed by I logon again to check.
This is a really bad solution, but currently the only one.
Regards,
Niklas
