Disk space errors since the upgrade to 12.1 RU5 or higher and some features aren't working anymore
Last Updated April 09, 2016
Symantec Endpoint Protection Manager (SEPM) was recently upgraded to version 12.1 RU5 or higher.
Since then, SEP clients are not communicating with the SEPM and some features (e.g. LiveUpdate, remote deployment, client install package export) are failing. Errors appear in %SEPM%\Tomcat\logs\scm-server-0.log, highlighting a disk space issue whereas there are gigabytes of free disk space available on system and SEPM drives.
SEP client connection status displays the error "503 Service Unavailable".

In previous versions, SEPM services ("semsrv" - Tomcat and "semwebsrv" - Apache) were running under local system account. As per security Best Practices, services should run with the lowest privileges necessary. Therefore it has been decided in 12.1 RU5 to change accounts used to run Tomcat and Apache:
- Network Service account is now used in Windows Server 2003/2008 and Windows XP
- Virtual accounts NT SERVICE\semsrv and NT SERVICE\semwebsrv are now used in Windows Server 2008 R2/Windows 7 or higher
NOTE - Because some SEPM features do require elevated privileges, a new service named "Symantec Endpoint Protection Launcher" has been created.
If the account under which Tomcat is running doesn't have READ access to root of drives involved (system and SEPM), the function used to calculate free disk space available would return incorrect values and cause SEPM tasks to be wrongly terminated.
Based on SEPM OS (see Cause section above), give READ access to system drive and SEPM drive for Network Service or NT SERVICE\semsrv.
