Limit MySQL usage

[kilgore]

Dear,

PHP got limitation : 30s execution time and 8 MBits memory usage but MySQL isn't getting any limitation.

I want to limit MySQL usage in order to ensure my server isn't going to be unstable.

I need to limit query execution time (not to log slow-queries) and number of query per second (per user or global).

Is this possible with MySQL ?

Any other idea appreciated

Best regards,

Kilgore
