Find out the problem of excessive cpu usage in java code When a java Process occupies too much CPU, it may be a logical problem. How to troubleshoot the problem? 1. Use the top tool to list all processes, and use shitf + p to list processes with high CPU usage 2. Locate the problematic process number and use top-H-p pid to list all threads of the process 3. shift + p then sort by CPU usage 4. Locate the problem process number and print its hexadecimal value in python, print ("0x" % ppid), for ex
