It takes so long to access Cloudera Manager that it's almost unreachable.

[#1]

Why is this happening? The installation went perfectly, but when I try to do anything else, it disconnects because the job is waiting too long. It's not like I'm running out of memory or anything. What could be the cause?

Hello @Lavenda 

Thank you for reaching out to community

Can you please confirm what is the heap assigned to CM server? You can check the same in /etc/default/cloudera-scm-server

Also, do you see JVM pauses in /var/log/cloudera-scm-server/cloudera-scm-server.log.

If you see JVM pauses in the above logs try increasing the heap for CM server and restart the cloudera-scm-server service (systemctl restart cloudera-scm-server)

# cat /var/log/cloudera-scm-server/cloudera-scm-server.log | grep -i "Detected pause in JVM"
