Out of Memory on classify(...,'ExecutionEnvironment','cpu') on SUSE Linux

I've got an issue with the classify function running on SUSE Linux. I've got a network which is trained for image analysis. When I try to classify new images (100-500) with the network, it takes a while until Matlab takes all the system memory (48gb) and eventually gets killed by the OS (i.e. the Matlab process just shuts down).
x=classify(net,beadImgs,'ExecutionEnvironment','cpu');
The same program works fine on a Windows machine with 16gb of RAM either with 'gpu' or with 'cpu' Execution environment (I cant test the 'gpu' Option on the Linux system). My guess is that this memory footprint is 'somewhat unintended'. Does anybody have an idea on how to fix this?
EDIT:
Okay I figured out a workaround. Manually setting the batch size fixes the issue for the moment. Nevertheless the different memory footprint on different operating systems is still mysterious.

What happens when you use 'Acceleration', 'none' in your call to classify. Does that make it work?

This response is just for future reference:
Modifying the Name-Value pair, ‘MiniBatchSize’, to a lower value can help with this issue. The default value is 128. If a similar issue is present during training, you can similarly set the same property in trainNetwork and imageDatastore to a lower value to help with this issue.
