ImageManip queue becomes empty after about 3 minutes of running

I'm using 2 ImageManips on a still - one to crop, another to resize

After running for 3 minutes, taking a still a second, the when I tryget the imageManip from its queue it becomes empty (or None).

I'm also capturing the still on a stream, and this isn't empty and continues to run fine. Does anyone know why this issue is happening?

Follow up on this - its actually the still being captured which becomes None after a few minutes

I've narrowed this issue down a bit:

It only occurs when:

I have an ImageManip thats XLinking out, as well as a still (which was originally passed into the ImageManip) XLinking out

This issue only occurs when I XLink it out, not if it just exists without a xlink out

Hi @userOfCamera
Do you mind adding a MRE? Are there any blocking calls in the pipeline?

Thanks,
