Ignition 8.1.30 PostgreSQL Database Available storage: Over 150 GB (dedicated drive) DB Connections: 10/10 Over the last couple weeks, the following error has flooded our gateway logs more and more frequently. Hundreds of log errors can be generated in less than a minute. What could be a potential cause or solution? Could viewing elaborate power charts be responsible? Anything else? So far the issue resolves itself, however each occurrence is lasting longer and longer. No known side effects have been noticed through the perspective front end, however the errors are trending in the wrong direction. Any help appreciated! ```auto query Error querying historical annotations for provider '{histprov/LocalDatabase}'. com.inductiveautomation.ignition.gateway.datasource.FaultedDatabaseConnectionException: The database connection 'LocalDatabase' is FAULTED.

Hi Jaron, At first glance it looks like your database connection may just be faulted and/or disabled. Please check the database connection settings and history provider settings to make sure that neither are disabled. Also, if you have been experiencing network outages on the gateway machine or database machine, that could be a cause. If none of those theories match your situation, then it would be best to open up a ticket with our support department. You can submit a ticket though the [Inductive Automation Help Center](https://support.inductiveautomation.com/hc/) and one of our support representatives can look deeper into this issue.
