Description
I am using scala arrow 1.0.1 and pyarrow 1.0.1
Following error occurs when scala decode the byte that encoded from python.
tried to downgrade pyarrow to 0.17.0, 0.14.1, error still exists.
This is a loop function to decode the same data repeatedly. The error occurs sometimes, and I use a try catch block to include the code. And after an error occurs, following code could still work correctly, but after the first error occurs, following error would happen more frequently.

Contributor guide
Research direction
Start by reproducing the repeated decode loop with Python-produced bytes, then trace the stack from ArrowReader and ArrowStreamReader through MessageChannelReader and MessageSerializer. The issue does not name a source file or test; done means the data can be decoded repeatedly without the intermittent ByteBuffer allocation failure.
