Network Security Manager becomes unresponsive
Technical Articles ID:   KB83829
Last Modified:  1/22/2015

Environment

McAfee Network Security Manager 8.1.7.5

Problem

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. 

Cause

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.

Solution

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
     
    To:
     
    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
