    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.
 
    key_buffer_size=268435456
    read_buffer_size=524288
    max_used_connections=5
    max_threads=151
    thread_count=4
    connection_count=4
    It is possible that mysqld could use up to 
    key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1094235 K  bytes of memory
    Hope that's ok; if not, decrease some variables in the equation.

Pouvez-vous m'aider svp ?

Impossible pour moi de faire repartir MySQL. J'ai donc finalement refait une nouvelle VM avec un import de la conf via CLAPI.
