I got into JVM issues yesterday. It’s actually trying to see what happened. What caused such a big jump in cpu.
It turns out it’s related to concurrency and threading issues. I read about this a while ago. Guess what? I still don’t really know how to read a thread dump? Does anybody know? Good question.
Lesson learned? Concurrency is one complicated topic. I need to learn, learn it. I need to read and re-read books on the subject. AND I NEED TO DOCUMENT EVERYTHING I LEARN ABOUT CONCURRENCY
