Hello Pavan,

Can you please let us know how much memory is allocated to Confluence? This configuration is set in the <confluence-install-directory>/bin/setenv.sh file, for example:

-Xms1024m -Xmx1024m -XX:MaxPermSize=256m -XX:+UseG1GC

In case you are running Confluence on a Windows as a service you'll need to check the service settings.

I Have increased the JVM Memory, it worked for me. Thank you :)

try adding  -XX:+UseConcMarkSweepGC to the JAVA_OPTS variable in the setenv.sh file.
