问题
I have developed a joomla website with a large database expecially the jos_users which is having about 2 million users..
I get this below error when i try to create a New contact in the backennd of joomla admin (contact component)
I have dedicated server and have told me host providers to see if there is changes to be done from their side or my side to the MYSQL server...
But they say the script needs to be optimized or something... below is are the ERRORs
Error Loading Modules
MySQL server has gone away
SQL:
SELECT m.* FROM jos_modules as m LEFT JOIN jos_modules_menu AS mm ON mm.moduleid = m.id WHERE m.published = 1 AND m.access <= 2 AND m.client_id = 1 ORDER BY m.position, m.ordering
Errors:

回答1:
That's one big jos_users table, but the query you're asking about doesn't include that table at all, so it may be the sql statement that ran just before that one. To see what it might be, turn on Joomla Debugging in the System Configuration, and see what the SQL statements are before that one - likely the last one on the page.
