Sometimes when you run ‘yum update’ or try to install or update softwares using yum, you will get ‘thread.error: can’t start new thread ‘ error.
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.
You can disable this plugin in 2 ways :
Login using root issue and issue this command.
And change this line
OR Login using root issue and issue this command.
yum --disableplugin=fastestmirror update
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.
yum --enableplugin=fastestmirror update
OR change enable=1 in fastestmirror.conf file.
