Hi,

I am using a flink task manager with 5-6 pipelines. When the task
manager reaches the number of threads to 900+ I am seeing performance
issues where the pipeline gets stuck while cancelling, restarting,
redeploying the pipeline. When the thread count is less than 800 I don't
see this problem.

   1. is there a limit on number of threads
   2. what is relation with number of tasks in pipeline to number of threads

Any documentation or pointers will help.

Thanks,
Abhishek
