WordPress database error MySQL server has gone away for query

I’m using the WordPress SEO by Yoast plugin and it’s really good. The only problem is that it gives a lot of errors and this causes Server downtime. My server had more than 1 hours of downtime because of this plugin’s errors. Here is the error log :

Is this a bug ? Is there a lightweight version of this plugin that I can use? My Blog : http://subinsb.com
