Possible reasons are:
1. You have an outdated OS.
2. You don't update your apps especially the Facebook App.
3. You always forget to kill every app after using it. Not exiting apps properly, still use some memory of your iPod.
4. You have too many music, video and apps in your phones.

Possible solutions:
1. Update your OS/Apps.
2. Reformat your iPod.
3. Exit your apps properly.
4. Delete some music/ video and uninstall unnecessary apps.
