Linu the Java program consumes high CPU and memory error handling scheme

1: View all process pid through the JPS command.

2: Use top-p PID to view the CPU and memory and load of the process for the PID you are looking for

Use top-p pid-h to view CPU-intensive queries for each thread

If you find that a certain PID CPU is too high, you can get this PID into 16 binary

For example, PID 12760 is converted to 16 binary 31d8, uppercase to lowercase

Jstack 22821|grep-a 0x31d8
For each of your threads to take out CPU-intensive stack information, you can use this to find the CPU
If you have a high memory footprint, I prefer to use the Jmap command  jmap -histo:live 9652 | head -n 100



Jmap-heap 12733
