MySQL error was: Too many connections.

MySQL error was: Too many connections. Just got this message a few minutes ago... our server is hosting other non-drupal cms and php programs (joomla, coppermine) ... checking on those other sites, the same errors are displayed, as well as in phpmyadmin (coppermine site, same error of "too many connections," while joomla sites has an error message just the same)...

therefore, i believe the problem doesn't lie in drupal's caching, might be a mysql issue (phpmyadmin settings)... might even be a php settings reconfiguration... will try reloading my database... will get back on this one...
