After a period of inactivity, the UI loses connection to the CP and the following window appears:




To resolve the issue I added the following line to the uc4config.xml:




<active_keepalive>time frame</active_keepalive>


Time in minutes in which the UserInterface sends messages to the Automation Engine in order to keep the connection.

This parameter does not depend on <tcpip_keepalive>. The setting <tpcip_keepalive> activates and keeps the connection on socket level which means that the time interval of keep-alive packages cannot be influenced. <active_keepalive> addresses the program level.

So now the uc4config.xml looks like:


 <docu type="hh">../../docu</docu>

 <!--docu type="wh">../docu</docu-->

 <!--browser type="Mozilla Firefox">/users/uc4/firefox/firefox</browser-->

 <logging count="10">../temp/UCDJ_LOG_##.TXT</logging>

 <trace count="10" ra="0" tcp="0" xml="0">../temp/UCDJ_TRC_##.TXT</trace>
