hello
i cant access the help.joomla.org now.
i have the following error :

mossession::store failed
DB function failed with error number 1062
Duplicate entry '1-' for key 2 SQL=INSERT INTO mos_session ( `session_id`,`time`,`username`,`gid`,`guest` ) VALUES ( 'ba2106e0371b7f7606ee19cc734f50ea','1132336738','','0','1' )

I just had the same error.

Yup, just as I send an email to someone looking for documentation, the help site goes down 

We're looking at it, and the problem will be resolved shortly. Thanks for the heads up!

db has been repaired and help is back.. cheers.

Thank you

Can anyone shed some light on this incident?  I'm receiving the same error as well and would love to know how to fix it

On your own server or this server?

My server.  I'm guessing it's a side-effect of a load spike on the database server, but I'm just wondering how this was resolved for help.joomla.org.

Normally, if databases become damaged, we run a Database Repair on it.  You can do this by running this query on the database table in question.
REPAIR TABLE (table_name);

You can run this from PHPMyAdmin if you aren't comfortable with using the command line.  If your server is running CPanel, you can go into the CPanel Database Management area and just click "Repair" next to the database.

Well, I don't think it was damaged because it resolved itself, and the error went away, but it'd be nice to at least know what caused this (and the solution) for future reference.
