In such situation I noticed, that response time of my SpringBoot application is significantly larger.

I do not flushed any thread dumps at theese moments.

EDIT: jvm parameters: java -Dcom.sun.management.jmxremote.host=localhost -Djava.rmi.server.hostname=localhost -Dcom.sun.management.jmxremote.port=7091 -Dcom.sun.management.jmxremote.rmi.port=7091 -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.access.file=etc/jmxremote.access -Dcom.sun.management.jmxremote.password.file=etc/jmxremote.password -Dcom.sun.management.jmxremote.ssl=false -Xlog:gc*,safepoint:file=/app/log/GC.log:tags,time,uptime,level:filecount=16,filesize=32M -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/app/dump/MemoryDump.hprof -Xmx10G -jar app.jar

At the time of occurrence of "Safepoint "ThreadDump"" I didn't try to connect any jmx tool.

Have you any idea what can be reason of such JVM behaviour? How can I avoid it?
