The default `jira.executor.threadpool.size` is set to 4. The Confluence instance heavily using Jira charts, there is a risk of exhausting this thread pool. When the pool is depleted, Confluence will start displaying the "Error rendering macro 'jirachart'" message when accessing pages with Jira charts.
Solution
To resolve this issue, you can follow below steps to increase the pool size.
Shutdown Confluence.
Take backup of <confluence_installer>/bin/setenv.sh file.
Edit the <confluence_installer>/bin/setenv.sh file and append the below line :
1CATALINA_OPTS="-Djira.executor.threadpool.size=10 ${CATALINA_OPTS}"Note : Make sure the parameter is added above export CATALINA_OPTS in <confluence_installer>/bin/setenv.shfile.
Start Confluence.
Make sure to make the above changes on all the nodes in the cluster.
