The solution to this error is fairly simple. You need to shutdown the confluence service from services panel. Go to bin directory under installation directory. As I was using windows environment so I used setenv.bat file to change the parameters of XMs: XMx and HeapSpace from standard 256M and 512M to 1024M for all of these options. Please changes these values according to your available memory parameters.

You can change the parameters from tomcat7w.exe or which ever version you are using like tomcat9w.exe. copy the path of this file from address bar and open a command prompt. enter the under listed command in command prompt to execute which will open the system properties. Go to Java tab to change the properties related to Java.

D:\path_to_tomcat\tomcat7w.exe //ES/Confluence_Service_Name(copy from services panel)


Change the initial memory pool and Maximum memory pool. Also change the HeapSpace size in Java Options to maximum possible (1024M).
