[daemon] High CPU load after update from 1.3.2 to 1.3.3
Hi there,
I see a high CPU load after updating commons-daemon from 1.3.2 to 1.3.3
(and 1.3.4) on my system.
The application is a simple SpringBoot application that is started with
service-user LocalSystem (no difference if started with default value).
How can I find the cause for this?
Many thanks,
Andreas

Hello,
I know that the statement "high CPU load" ist pretty vague, but the CPU
load in Windows task manager was the only visible thing I saw. No different
logs even with LogLevel=DEBUG.
But I found out that removing the StopTimeout parameter (in my case
--StopTimeout=15) solves the issue. So I think it might be related to this
change:

Andreas,
Use the java flight recorder to take a recording of a minute or two. Open it in Java Mission Control and look at the method samples. That will give you a good idea where the CPU usage is coming from. If that doesn't seem helpful, maybe enable -XX+DebugNonSafepoints and try again.

The statement "high CPU load" is pretty vague. Gathering data on which
processes use what percentage of CPU/cores and disk activity over time
would be a start.
