I have this error message (error.log) : [ Jul 28 2008 16:07:43 ] [86.67.69.64] eZMySQLDB: Connection error: Couldn't connect to database. Please try again later or inform the system administrator. Lost connection to MySQL server during query There is about 500 users connected at the same time. Is there a relation (?) between users request and cache rebuilt ? Any hints ? Best regards. laurent Ps : on the pre-prod site there is no crash

Hi,

I have a site which tooks a very very long time to rebuild caches after clearing cache-block and template cache.

I have this error message (error.log) :

[ Jul 28 2008 16:07:43 ] [86.67.69.64] eZMySQLDB:
Connection error: Couldn't connect to database. Please try again later or inform the system administrator.

There is about 500 users connected at the same time.
Is there a relation (?) between users request and cache rebuilt ?

Any hints ?

Best regards.
