How does the Health Check diagnose JVM Code Cache problems?

Frank Schimmel October 27, 2020

Hello everyone,

we have repeated Health Check error messages "JVM Code Cache", but in Tomcat's catalina.out there is only one occurence 4 weeks ago, because we have increased the 

-XX:ReservedCodeCacheSize=384m

as recommended.

My assumption is that Confluence's Health Check has repeatedly reported the old log file entry because this entry was still in the log file.

Is it a true assumption that the Health Check analyzes catalina.out to report the JVM CodeCache error? The reason why I am asking: after we have emptied the catalina.out, Confluence has not reported the error again. 

Thanks

Frank

Hi!

Just curious do you use the latest version of support and diagnostic tools ?

as experiment, you can just move catalina.out -> catalina.out.1 and create a new one catalina.ou
