yum update error : thread.error: can’t start new thread
This error is due to the inadequate memory for yum operation. This occurs due to Yum’s fastest-mirror plugin. So, if you have a low end VPS then you may see this error often. To solve this just disable that plugin.

This plugin is used to find the fastest mirrors/sources available for the software so that the update/install process is quicker. To re-enable the plugin, just run the command.
