using jenkins version 2.235.2 for CI/CD and its not closing threads automatically.when new pipeline run its creating new threads and keeping all plunging file details in that thread open(around 20000 files on each thread). thread count is getting increase until not restart Jenkins. when we restart at that time thread count around 250 and after 4-5 day if we are checking thread count is around 1000.
even we tried with garbage collection but after that also thread count in not decreasing
