I have a Unity3D application that crashes every now and then, and I am a bit lost trying to decipher the crash logs.
A common theme I've found is that in all the logs the line "DynamicHeapAllocator out of memory - Could not get memory for large allocation" occurs. So, it ran out of memory, right? But how do I know how much it was allocating, or what for?
I notice that some logs output some more data:
DynamicHeapAllocator out of memory - Could not get memory for large allocationCould not allocate memory: System out of memory!

Crash!!!
I'm -guessing- the problem here lies in ALLOC_DEFAULT, because it has 4428944B reserved and 36395388B in use, which does not leave enough memory for the 1048588B it is trying to allocate, is this correct?
I am wondering though, if these numbers are in bytes, why it can't just reserve more memory. Why is it only reserving only roughly 44 megabytes?
The line "Allocation happened at: Line:102 in" is also frustratingly cut short. If I knew what file or method it occurred in, I might be able to debug my scripts. How do I obtain this information?
One of the other crash logs offers even less information. Rather than the memory overview it just states
DynamicHeapAllocator out of memory - Could not get memory for large allocationCrash!!!

And then a whole list of other dll's.
I'm kind of at a loss. How do I narrow down what is causing the problem based on this information?
