The solera-gaugefs service stopped for some reason. The service was restarted automatically. When looking at /var/log/messages we see this error:

Release : 8.2.2 and prior
This is caused by a memory mismatch issue in the gaugefs process.
This has been resolved in Security Analytics version 8.2.4 and greater. Note that this will not affect the ability for the appliance to capture and index traffic. The solera-gaugefs process is the report service and is only invoked when a report is requested on the appliance.
