McAfee Network Security Manager


Network Security Manager becomes gradually less responsive, and eventually stops responding. To force the Manager to start working, you restart the services or perform a reboot. 

In the Performance Monitor you see that the java.exe process uses 20% more RAM each day. After all the memory reserved for the Java is used, CPU usage rises to 100% and the Manager become unresponsive. 


When the volume of alerts is very high the SOLR database can use a large amount of memory and exhaust the available resources, making the Network Security Manager unstable due to lack of memory.


Increase the Network Security Manager heap from 4 GB to 6 GB via the tms.bat:
  1. Launch Windows Explorer.
  2. Open D:\Program Files (x86)\McAfee\Network Security Manager\App\bin\tms.bat in a plain text editor such as Notepad.
  3. Locate the following line:
    set JAVA_OPTS=%JAVA_OPTS% -server -Xms2038m -Xmx4076m -Xss128K
  4. Modify the line from:
    set JAVA_OPTS=%JAVA_OPTS% -server -Xms2038m -Xmx4076m -Xss128K
    set JAVA_OPTS=%JAVA_OPTS% -server -xms2038m -Xmx6144m -Xss128k
  5. Stop the Network Security Manager service.
  6. Save the file.
  7. Start the Network Security Manager service
