Web Player: DynamicHeapAllocator out of memory

I am getting this error message (DynamicHeapAllocator out of memory - Could not get memory for large allocationCould not allocate memory: System out of memory!) for my Web build. It runs fine for Standalone, Android, and iOS builds; and occasionally works on FireFox. I came across this thread, which sounds exactly like what I am experiencing; but there is no solution posted.

I am using version 4.5.5. Any help or insight will be appreciated.

Okay, after some digging with the profiler. I have found that it was the GUI textures I am using causing the memory crash and that it looks like IE only allows ~1.25 GB of memory to be used. After reducing the size of the GUI textures it runs fine.
