"JVM" Jstack queries consume maximum resource threads | Troubleshoot dead loops, etc.

Jstack applications

First by: Ps-ef|grep Java

Get the Java PID

See which thread is consuming the most resources:

Find out the CPU-intensive threads in the process, and use the PS-LFP pid or ps-mp pid-o thread, Tid, time, or top-hp PID command to see all the thread usage under the process.

found that thread 21742 occupies the most.

Convert the most CPU-intensive thread ID (21742) to 16 binary

命令：printf"%x\n"21742 的到 线程值 ：54ee

To view Jstack generated files:

Jstack PID | grep tid

Example: Jstack 21711 | grep 54ee

Below you can see which line of code is causing the line of code to see the dead loop. The trace is resolved.
