There are two issues here:
- Users are seeing site error messages that they shouldn't
- The error message itself
For 1, go to admin/config/development/logging and set Error messages to display to None. Don't worry, this won't affect messages like "incorrect login details" or "page not found, we did a search instead" ... things that the user really needs to know.
As for 2, here are a couple of things to try:
- Turn off all your custom modules if you have any, re-enable them one by one to see if you can find the cause
- Do the same with contributed modules
- Read up on the error message, there are too many things that could be causing it that are non-drupal specific to be useful on this site.
