Full GC产生原因是啥



下列Full GC产生原因是啥,如何解决调整

[   Full GC (Allocation Failure) 2020-10-28T19:58:47.153+0800: 8809.366: 
    [
        CMS2020-10-28T19:58:48.325+0800: 8810.538: [CMS-concurrent-mark: 1.418/1.454 secs] [Times: user=9.69 sys=0.16, real=1.46 secs] 
        (concurrent mode failure): 1966079K->1966079K(1966080K), 7.7026651 secs
    ] 
    2948938K->1985539K(2949120K), [Metaspace: 49449K->49449K(1093632K)], 7.7034577 secs
] 
[Times: user=12.35 sys=0.00, real=7.71 secs] 

jvm参数设置如下

JAVA_OPTS="-server -Xms3g -Xmx3g -Xmn1152m -Xss512k -XX:SurvivorRatio=4"

JAVA_OPTS="${JAVA_OPTS} -XX:+UseBiasedLocking -XX:-TieredCompilation
-XX:+AlwaysPreTouch -Djava.awt.headless=true"

JAVA_OPTS="${JAVA_OPTS} -XX:+UseParNewGC -XX:+UseConcMarkSweepGC 
-XX:+CMSScavengeBeforeRemark -XX:+CMSParallelRemarkEnabled
-XX:+ExplicitGCInvokesConcurrent"
