Hi,    I've been using cloudera manager for the last one year with running of 20+ nodes. Recently i started to see heap memory size issue in Service monitor roles. I've increased from 3 to 4, then 4 to 5, and then 5 to 6 GB.But still i sometime get the service monitor crashed and restarted. During the time, the entire dashboard seems bad. What i need to do here to fix the issue?.    Logs are 2021-04-26 16:10:34,938 WARN com.cloudera.enterprise.debug.JvmPauseMonitor: Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 20583ms: GC pool 'G1 Young Generation' had collection(s): count=2 time=182ms, GC pool 'G1 Old Generation' had collection(s): count=1 time=20877ms 2021-04-26 16:11:34,862 WARN com.cloudera.enterprise.debug.JvmPauseMonitor: Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 19870ms: GC pool 'G1 Young Generation' had collection(s): count=2 time=131ms, GC pool 'G1 Old Generation' had collection(s): count=1 time=20228ms 2021-04-26 16:12:35,132 WARN com.cloudera.enterprise.debug.JvmPauseMonitor: Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 20427ms: GC pool 'G1 Young Generation' had collection(s): count=3 time=149ms, GC pool 'G1 Old Generation' had collection(s): count=1 time=20733ms 2021-04-26 16:13:36,415 WARN com.cloudera.enterprise.debug.JvmPauseMonitor: Detected pause in JVM or host machine (e.g. a stop the world GC, or JVM not scheduled): paused approximately 19008ms: GC pool 'G1 Young Generation' had collection(s): count=1 time=104ms, GC pool 'G1 Old Generation' had collection(s): count=1 time=19381ms   Could you please help me on this?.  ...
