Hi @nkp,   What is your Cloudera Manager version?   To follow up with gziglgldrum's post, in case you can not access the article, here are some details copied from there:   To configure the maximum heap size of the SCM process, please do: 1) Edit the CMF_JAVA_OPTS property in the /etc/default/cloudera-scm-server file. 2) Alter last line of the file: export CMF_JAVA_OPTS="-Xmx2G -XX:MaxPermSize=256m ..." 3) To configure more heap memory to Cloudera Manager, please change -Xmx2G to bigger value. For example, -Xmx4G. Note:  -Xmx2G option specifies 2 GB of RAM. 4) Restart Cloudera Manager by running below command: sudo service cloudera-scm-server restart   You may also want to read this documentation to find out what is the recommended heap size for your Cloudera Manager: https://www.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_hardware_requirements.html#sizing_cm_server_reqs   Thanks and hope this helps, Li ...
