O MySQL travou porque não conseguiu alocar o 29.6G para o buffer pool.
"Sem memória.
Queremos manter todo o céu,
Mas nós nunca iremos. "
Estou enfrentando problemas para instalar um pacote de software que depende do MySQL. Durante a instalação, ele instala um servidor MySQL, mas, por algum motivo, o início dos serviços falha e, portanto, a instalação falha. Estou executando um servidor virtual Debian 7 (64 bits), nova instalação, sem plesk.
[FAIL] Starting MySQL database server: mysqld . . . . . . . . . . . . . . failed!
Quando eu corro sudo -u mysql mysqld , ele retorna o seguinte:

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

It is possible that mysqld could use up to

Hope that's ok; if not, decrease some variables in the equation.
