  • I receive an error regarding the temporary store limit when the broker is started:
| ERROR | Q Broker: fusemq | BrokerService                    | 125 - org.apache.activemq.activemq-core - 5.7.0.fuse-71-047 | Temporary Store limit is 51200 mb, whilst the temporary data directory: C:\fuse\fuse-esb-7.1.0.fuse-047\data\fusemq\fusemq\tmp_storage only has 16417 mb of usable space

Hawtio health menu shows error, HealthID: org.apache.activemq.FreeDiskSpaceLeft


To resolve this error you should limit the broker's temporary store limit to a value that is available on disk. This value is set in the broker's system usage configuration by the tempUsage limit:

          <memoryUsage limit="64 mb"/>
         <storeUsage limit="100 gb"/>
         <tempUsage limit="50 gb"/>

While the broker may perform ok at first with this condition it has the potential to lead to unexpected results such IOExceptions rather than triggering Producer Flow Control when the resources are exhausted. It is recommend to fix this situation by adjusting the usages limits appropriately.

Root Cause

The broker has requested to allocate more disk resources than what is available. See this article for more details of how to tailor the Broker data stores.
