Thanks Razvan. Increasing the RootAllocator limit resolved the problem.

Hi Tanveer, The stack trace seems to indicate that you you've breached the limit of the allocator used by the ArrowStreamReader, so that's where I'd look first. The limit is usually set when constructing an allocator (e.g. new RootAllocator(myLimit)) or when getting a child allocator (e.g. rootAllocator.newChildAllocator(...)).
