Minecraft pe host crash bug

When I play minecraft pe multiplayer over local wifi if I host every 5 to 10 minutes it will crash on my ipod

The game should continue hosting multiplayer as normal

But instead every 5 to 10 minutes the hosting ipod will crash

For this to happen all I had to do was host a world on minecraft
Then have someone join
Then it would eventually crash
P.S. this happend to 2 other people I know 1 had an iPad 3 the other had an ipod 3
