High CPU Usage in Spring Boot Application with Redisson: MapCacheEvictionTask Issue

Question

• I'm facing persistent high CPU usage in my Spring Boot application. The error when analysing heap dump: **instances of **"org.redisson.eviction.MapCacheEvictionTask", loaded by "org.springframework.boot.loader.LaunchedURLClassLoader @ 0x63d034430"

  Configuration Details:

  • Redisson version: 1.7.11.RELEASE

  • Spring Boot version: 2.2.2.RELEASE

     <dependency>
         <groupId>org.springframework.data</groupId>
         <artifactId>spring-data-redis</artifactId>
         <version>1.7.11.RELEASE</version>
     </dependency>
    

  I have checked the Redisson and Spring Boot documentation for guidance and used the latest redis version as well which is 3.1.8
