For the last two nights (since upgrading to 2.6.0.25) I have had the issue that after a few hours of imaging - between 100 and 120 subs (plus more from running AF every half hour) SGP starts failing with the error:
[12/10/2017 10:43:59 PM][Warning] (N925) Error attempting to capture image (see logs for more information).
[12/10/2017 10:43:59 PM][Status] (N925) Failed to save image to disk!
If I quit SGP and then restart it the error clears and I can run for another 100-120 images or so before the error happens again. This sure looks like a memory leak - or some other resource that is being allocated once per image and not being appropriately freed.
