How does the Health Check diagnose JVM Code Cache problems?

Frank Schimmel_nfktbo

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
