Memory Information screen shows 0% free metaspace in Jira server
Platform Notice: Server and Data Center Only - This article only applies to Atlassian products on the server and data center platforms.
The Memory Information under Administration > System > System Info displays 0% Free MetaSpace:
- JIRA applications running with Java 1.8 or later.
- The -XX:MaxMetaspaceSize JVM argument is not configured.
This is the expected behavior.
Java 8 replaces the PermGen memory area with MetaSpace, which is dynamically allocated on native memory. The amount of native memory that can be used for class metadata is by default unlimited and managed by the JVM automatically.
No action is required - This is the expected behavior.
