The only way you'll be able to tell what is causing those CPU spikes is
with a profiler. Once you know that, then we might be able to help by
suggesting mitigations.

Question regarding changelog in 8.5.46

2019-10-02 Thread M. Manna
Hello,

http://tomcat.apache.org/tomcat-8.5-doc/changelog.html#Tomcat_8.5.46_(markt)


I am just trying to understand if these changes have any impact on 8.5.45
with CPU usage. It seems to be some potential NPE and (HTTP/2 only) hanging
issues.

We are seeing some CPU spikes with 8.5.45 and these changes don't seem to
be directly responsible for fixing the issues. So, just trying to eliminate
the need for jumping to another upgrade.

Sorry again for any unintentional spam.

Thanks,
