Having the same problem.

Are you using a Flatlist? As it keeps re-rendering I think the FLatlist keeps building on

Im having same problem. I think that because of react-native-snap-carousel components and that components using flatlist

same problem, resulting in freeze of application after some time, caused by slider, I do change the image array a few times which could be an issue, seems to build up a large list then freeze
