black images when storing checkpoints on CIFS share

I've had the issue that when I load a model there is a very high chance that all the images that I generate are just black and that I get a error in my terminal (`invalid value encountered in cast img = Image.fromarray(np.clip(i, 0, 255).astype(np.uint8))`). After restarting Comfyui a lot of times it would work, but if I used another checkpoint the issue would happen again. Ever since I moved my models from a CIFS share (uid and gid where set to the user which ran comfyui) to a ISCSI disk with ext4 this issue doesn't happen anymore. This behavior isn't new and has plagued me for months.
