More specifically:

Use -e"SHOW STATUS LIKE 'Max_used_connections'" to get an indication of the 
number of connections you're seeing. Calculate your memory usage with that 
value, then see if it goes above memory limits.
Then try adjusting the key_buffer_size since it's globally allocated.

Note that this requires tuning. A lower key_buffer_size can mean that queries 
take longer, which in turn will increase your memory usage.

Things are more complicated with InnoDb.


Problem with today's modular software: they start with the modules
    and never get to the software part.
