Why does my server hang up all the time?
System Overload. Server hang-ups due to system overload typically show up as slowly loading pages. The system may respond slowly for a period and then return to normal operation. Server slow downs typically happen at peak traffic periods, when scheduled tasks (cron jobs) run, or when certain maintenance occurs.
How often does rackaid get reports of servers being down?
Local, regional or at the data center, rackAID receives reports every week of servers being down or frozen. Typically, clients say they cannot get to the website or get a web site not found error. In most cases, the server is fine, but there is a network problem. I use Alertra’s Spotcheck to verify a site is up.
How to manage database timeouts and cancellations in go?
The timeout countdown begins from the moment that the child context is created using context.WithTimeout (). If you want more control over this you could use the alternative context.WithDeadline () function, which allows you to set an explicit time.Time value for when the context should timeout instead. OK, let’s try this out.
When does a query take longer than expected?
Two scenarios spring to mind: When a query is taking a lot longer to complete than expected. If this happens, it suggests a problem — either with that particular query or your database or application more generally.
When to take a snapshot of the database?
Database snapshots are always taken of the database in a consistent state. If a large transaction has been running for, say, 10 minutes, the transaction has to be rolled back in the snapshot before the snapshot can be complete. The above query can tell you what’s running at the time it is run.
How long does it take to execute a query in MySQL?
If you have a very large table in MySQL with an index, and you execute this for the first time, it may take 2 minutes. While if you execute it again it will return right away. You can use the Help-> [SQL Log] to help diagnose the query execution speeds.
Why does SQL Server get a database stuck in?
The database in question has DATABASE_SNAPSHOT_CREATION, and even tough the docs say it should be a momentary state, it’s been in this state for 10 mins. I’m guessing it’s what’s keeping the log from becoming manageable.
