think of what could be causing it. Stranger yet, rebooting the server fixes the issue. Any ideas? Viewing 6 replies what does error establishing a database connection mean - 1 through 6 (of 6 total) ashiquzzaman @ashiquzzaman 1 month, 2 weeks ago Did you try the basic troubleshooting techniques like - changing your theme to default WordPress theme and then reverting back error establishing a database connection website to your themes or disabling your plugins one by one and see if it fixes the issue. tenhourguy @tenhourguy 1 month, 2 weeks ago My theme is the default (Twenty Sixteen). Um… I could try disabling plugins one by one but that could mess up my site's functionality a little, especially as I'd have to leave each one disabled for several weeks since the error timings are inconsistent.

suspect my database optimiser plugin is to blame but nothing goes wrong when manually running it and the database errors occur at inconsistent times rather than after midnight, when it runs automatically. Hmm… Sorry for being so vague. :/ tenhourguy @tenhourguy 1 month, 2 weeks ago Okay, at wordpress.org/support/topic/seemingly-random-error-establishing-a-database-connection, this person has the same issue and even the same host. I'll try adding a swap file, perhaps the same size as my RAM later, since 512MB isn't a great deal. Does that sound reasonable? Moderator Mark Ratledge @songdogtech 1 month, 2 weeks ago If that's your own server, you need to look at the logs: mysql logs for crashes, raw logs for traffic spikes that could cause loads, etc. It's really got little to do with WordPress at this point; it sounds like server admin. Nothing in WordPress is going to cause intermittent database connections unless it is a plugin running wild. Check your logs and php configs, MySQL configs, etc. If you have definite errors in logs, try http://serverfault.com/ tenhourguy @tenhourguy 1 month, 1 week ago Thank you, Mark. I will look into how to view logs, but if it is just a lack of RAM then it's probably no big deal.

Each database is used by a WordPress front end also hosted in Azure App Services. When using my WordPress sites, I will randomly receive: Error establishing a database connection. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. The user/pass for the databases in wp-config are correct because it will work and then not work and then work again in http://serverfault.com/questions/750238/how-to-diagnose-random-error-establishing-a-database-connection-with-wordpress the span of 5 minutes.

This is a scary error establishing one, because you'll likely be able to access, in part, either the front or back end of your website -- and, if you haven't yet gotten your head around a few fundamental concepts about servers and/or web development, you'll probably be at a loss. Here's how to go about understanding and troubleshooting this unnerving error establishing a error. What Does ‘Error Establishing a Database Connection' Actually Mean? Instead of being saved in specific files, the content of WordPress posts and pages is saved in a database that WordPress needs to reference each time it serves/generates a webpage. When a post gets viewed, for example, WordPress finds the database host, connects to its database, finds the WordPress posts table within that database, and looks up the content it's trying to load. In short, the infamous ‘error establishing a database connection‘ means that WordPress cannot find this database. Why is this such a big issue? Well, in addition to the content of posts and pages, WordPress also stores a whole heap of other essential information in its database -- such as its main settings, your user data, your selected theme, your widget settings, data for your active plugins, and so on. If WordPress can't access any of the information within its database, it has no way

After the migration I sometimes randomly receive "Error Establishing a Database Connection". Though I have tried various methods to fix this problem I still get the random errors. Additionally the only way to access the db is only by the Adminer wp plugin after I login to wordpress and via mysql command line. Adminer will not let me login if I use it as php script out of wordpress. I use mysql 5.5 with nginx 1.4.1 and php5-fpm with unix socket. Strangely enough the posts are not shown immediately after publish also after the migration. MySQL logs are always empty. The only workaround I found was that I had to manually restart the mysql daemon after the error in order to temporarily fix it until the next random error. In my mysql user passwords I include symbols. Is this somehow affecting the behaviour of the mysql server or the database connection? Should I try to repair the database? Any suggestions? php mysql wordpress nginx share|improve this question edited Aug 28 '13 at 12:04 nico_ekito 17.5k43867 asked Aug 28 '13 at 11:42 Evan Sap 1402517 Same here.
