Eu realmente preciso de algum conhecimento sobre mysql. Eu sou um novato no mysql e estou vendo alguma falha no servidor do meu banco de dados na última semana 1.
Estou usando o mysql 5.1.36 no Ubuntu. Este é um servidor mysql dedicado com dual core e 4GB de memória e 40GB SSD.
Os erros de registro são:

Alguma sugestão o que posso mudar.
