Deployed spring boot jar on linux machine is not responding!

Hello Prateek!

 Greetings.
 
 Your application is having a thread pool by name 'XNIO'. Threads in this thread pool are growing infinitely. 
 
 Above is the excerpt from the 'Thread Group' section of the report. You can notice that this thread pool has 1169 threads and more than 95% of those are in WAITING state, doing nothing.
 
 Below is the code stack trace of one of the XNIO threads. 95% of threads in this thread pool is having the exact same stacktrace:
 

XNIO-2 task-1000
THREAD ID :1216
STATE :WAITING

stackTrace:
at java.lang.Thread.run(Thread.java:748)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1134)
at java.util.concurrent.ThreadPoolExecutor.getTask(ThreadPoolExecutor.java:1074)

 You need to check why this thread pool is having these many threads? Are you setting max limit on this thread pool? WHy threads in this pool aren't reused? This can definetly cause unresponsiveness in your application.
