I don't know of ways to determine this in advance. Eventually all we can do is thry what you did: increase the malloc arena when it turns out to be too small.
If you are willing to invest a little more time, it would be interesting to test how much memory is actually needed on your system.
I know that 1MiB was too little and 4MiB was enough. However, I don't know whether a filesystem corruption could occur that caused ubifsmount to require more than 4MiB. For that reason I made the malloc area 64MiB. This is half my total RAM, which leaves the other half for downloading images.
