More than 15 days of CPU utilization increased for only Master Jenkins. However, slave Jenkins resources (RAM & CPU) is in a normal state.

Attaching thread dump of Master Jenkins process. What could be the problem and what is the fix for this?

Thanks & Regards

Hi Dhaval,

A single thread dump (or even multiple) is not enough to see why the server is consuming excessive cpu.

https://stackoverflow.com/a/29148553 will show how how to track the CPU to a specific (or set of) java threads.

Once armed with that, then the thread dump will help us see what those threads are doing and may give an indication as to how you can fix or prevent it (or if it looks to be a bug aid in filing a detailed bug report)
