Recently (this week) my sites (all wordpress) have been getting this error "Error establishing a database connection" a LOT.
At this point in time, I am effectively out of business.
The traffic and number of users has not increased significantly in the last month. My site is being throttled, but a test site allza.info has no users and no complex queries and no traffic (and the "DailyNotes" ElegantTheme), but still gets that intermittent error. So I'm focusing on that one thinking that if I fix it there, then the busy sites will get fixed too. allza.info is part of a multisite installation but chowstalker.com is a single installation and they both have the same problems.
The phpMyAdmin, fillezilla, and the bluehost stats and logs and various utilities do not show anything obviously down or slow, but the wordpress sites have become progressively slower with that error coming up now more than half the times I refresh a page.
I do have a trouble ticket into bluehost but they have not responded yet. The chat guy told me to enter a ticket.
Does anybody here have a clue on what I can do to fix this. Bluehost has been good so far, so I had to pull the plug and move to a "better" host.
I saw something about Zend Optimizer may be misconfigured, but would that help with the database connectivity?
Thanks all, Ron
ps: I posted this exact message on the bluehost forum.
