ERROR: Could not find a source for updated packages [0x00000071]

Question

Hi, 
 I have ERROR (Could not find a source for updated packages [0x00000071]) on Sophos Enterprise Console 5.4.1. These Computers randomly reports this error. They can report 5 or 10 successfully updates and then reports that could not find source... I have configured Sophos Update Manager and Sophos Enterprise Console on the same server. Also on this server run's apache that is the primary update server for endpoint's UNC as secondary. Updating schedule are set to 180 min. When I manually set to these computers Update now, fast every Computer updates successfully.

Hello Mantas Lenza , 
 Linux OS should be able to update via UNC as well, though depending on the distribution it might be necessary to install the cifs-utils or equivalent. 
 network traffic when checking for updates the endpoint uses catalogs (the .upd and if required .dat files) to assess whether something and what has changed. So most checks should result in only minimal traffic. Traffic volume is normally not a concern, it's establishing and taking down connections (and this has mostly an impact on the server). As you can expect actual updates several times a day an interval of 180 minutes will only add to updating latency (i.e. increase the time until detection data updates are available on the endpoint). short updating time dramatically increases updating errors As mentioned the server might be the bottle-neck - but for meaningful statement knowiledge of the nature of these errors would be required. 
 Please start a new thread for the scheduling issue.
