Scenario: Your JIRA system logs show repeated database connection errors. How would you diagnose and resolve this issue during routine maintenance?

Repeated database connection errors can indicate issues with the database server or connection settings. Checking the database server status and connection settings can help diagnose and resolve the issue. Restarting the JIRA application server may temporarily alleviate the problem, but it may not address the underlying cause. Increasing the maximum connection pool size can help accommodate more simultaneous connections, but it may not resolve issues related to connection errors. Purging old data from the database can free up resources, but it may not directly address connection errors unless the issue is related to database overload.
