Caused by: java.lang.VirtualMachineError: out of space in CodeCache for adapters

診断

The instance will have crashed, locked up or frozen, but once restarted the instance will continue to perform normally until the next freeze/hang/crash.

原因

The reason this occurs isn't clear, but the problem is that the CodeCache of the JVM becomes full and as a result the JVM locks up and the instance will crash.

ソリューション

• Add the following argument to the Java startup options by following these instructions.

  -XX:+UseCodeCacheFlushing

• Restart the application to initialise the new configuration.
