MYSQL Crash

[Lee Harper]

Hi there,

MYSQL keeps crashing and I'm not sure what to do.

From mysqld.log I'm getting this each time I run my multi thread script.

120808 18:49:14 mysqld_safe mysqld restarted
120808 18:49:15 [Warning] /usr/libexec/mysqld: Option '--set-variable' is deprecated. Use --variable-name=value instead.
120808 18:49:15 [Warning] '--log_slow_queries' is deprecated and will be removed in a future release. Please use ''--slow_query_log'/'--slow_query_log_file'' instead.
120808 18:49:15 [Warning] '--safe-show-database' is deprecated and will be removed in a future release. Please use 'GRANT SHOW DATABASES' instead.

120808 18:49:20 [Warning] Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--relay-log=mysqld-relay-bin' to avoid this problem.

120910 18:21:27 mysqld_safe Number of processes running now: 0

My PHP log is outputting [nativecode=2006 ** MySQL server has gone away]]
I'm also getting the error mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
And
nativecode=2013 ** Lost connection to MySQL server during query

Thank you for any help, or pointing me in the right direction for troubleshooting!
