Bug when joining world on iPad

So one day I was getting on to Minecraft and I was joining a world until this message came up when joining a world. The world I had was big and I do use lots of storage, I am using a iPad 5th. Anyways after there were about 3 messages that came up all of them did say error and then it kicked me out of Minecraft And I had about 7 add-on. Anyways when you have the time can you solve this Thanks
