Can someone help me to analyse why there are so many waiting and blocked threads? Can you suggest me something to fix?

    Hello shivanigarg60,

    Greetings!

    There are no major blocked threads, but as the report indicates, almost 60 plus threads are waiting under the     sling-threadpool-f11df4be-0156-4165-8c57-6fe65398fddf-(apache-sling-job-thread-pool) threads and HealthCheck idle threads. You can focus on these two threads and identify the root cause.

     

     

    Please find the stacktrace of these 2 threads below for your reference,
