Re: JVM Metaspace for Task Mangers and Job Managers are not getting released.
Hi Ajinkya, The command 'jcmd GC.run' can be used to trigger fullgc for JVM process. However, it should be noted that this may have a performance impact on the ongoing computation.

Re: JVM Metaspace for Task Mangers and Job Managers are not getting released.
Hi Ajinkya, The memory of metaspace may need to be released through FullGC, you can try to trigger fullgc manually in JobManager and TaskManager, and check whether the metaspace is released.

Re: JVM Metaspace for Task Mangers and Job Managers are not getting released.
Hi, Ajinkya Maybe some threads in your job were not shut down when the job was closed? Best, Jiadong Lu On 2023/5/13 4:58, Ajinkya Pathrudkar wrote: Hello, I am observing JVM Metaspace memory for Task Managers and Job Manager is not getting released. Any thoughts? image.png Thanks, Ajinkya
JVM Metaspace for Task Mangers and Job Managers are not getting released.
Hello, I am observing JVM Metaspace memory for Task Managers and Job Manager is not getting released. Any thoughts? [image: image.png] Thanks, Ajinkya
