why docker container consume huge CPU load average

I want to discuss about strange behavior on our rhel 7.6 server We installed Kafka exporter with container on the server – kafka-01 machine ( total CPU on machine are 12 ) The following yml file described the Kafka exporter container configuration more docker.kafka-exporter.yml --- version: '2.4' services: kafka-exporter: mem_limit: "612m" image: kafka-exporter:v1.2.0 restart: always network_mode: host container_name: kafka-exporter command: ["--kafka.server=kafka01.sys65.com:6667"]ump ports: - 9308:9308 logging: driver: "json-file" options: max-size: "15m" max-file: "1" so when we start the container with dockr-compose , as docker-compose -f docker.kafka-exporter.yml up -d we notices that CPU load average jump from ~2-3 to 30-40 after 1-2 hours and only restart of machine return the normal CPU load average to normal ( around 1 - 2 ) , but again CPU jump each time we start the docker compose , ( even stopping the docker compose not decrease the CPU load average ) can someone gives some hint what could be the reason for that strange behavior ? regarding our case is it useful to consider to install the https://github.com/draios/sysdig , for investigation ? Notes: We verified the CPU load avrg from uptime linux command *sometimes machine became **freeze** or **HANG** so we cant access the machine , and only reboot help to return machine again to normal*
