Hi,
Thanks for the quick response. Yes its spring boot application and
packaged as War file. The Tomcat running as windows service using Apache
common daemon.
I'm also attaching the stack trace observe in memory analyzer.
You need to look at the heap usage to see where the memory is being used.
Most profilers should also be able to tell where the CPU time is being
spent.
Did you look at DAEMON-460? Does it apply to you?

Hi,
I was using tomcat 9 with JDK 17 on windows. My java application
was using 2.7.18. Now I'm migrating my application spring version
to 3.3.4 with Tomcat 10.1.30 and JDK 21. I have upgraded the
version in my java project and fix the hibernate error migrating
from 5 to 6. Now my application start on tomcat 10. But after few
request JVM consume the maximum memory (I set it 3GB max) and cup
usage to 90-98%. I set windows service priority to low and it take
80-90% hence my application stop responding. Here is the thread dum
for the tomcat.Not getting any clue whats causing to tomcat high
CPU and memory usage.
A profiler (I use YourKit because they give free licenses to OSS
develoeprs but other profilers are avialable) will tell you more
about what is going on than a single stack trace.
Is this a Spring Boot app? Is it packaged as a JAR or a WAR?
How are you running this as a Windows service? If you are using
Apache Commons Daemon (the default way to run Tomcat as a Windows
service) then this might be useful:
