MySQL, despite its ease of use and popularity has a dark side of instability and crashes. Communities have forked MySQL, now an Oracle subsidiary (that was once a Sun subsidiary…), spawning alternatives like Percona, Drizzle, and MariaDB to improve quality and keep MySQL a viable database server. Newer servers (platform version 4.5+) use alternatives like Percona and MariaDB. Stability is much improved over MySQL, but crashes may still occur.
There are a variety of causes ranging from known bugs, unknown bugs, exceeding your storage limits, and tidal effects of the moon. Errors are presented in either the application itself or error logs of the form,
