I'm trying to run a seamless mosaicking procedure on a relatively big dataset (25 images, 186 bands per image, roughly 1400*6100 pixels per image).
The procedure starts correctly, the progress bar fills completely, but the process never finishes. Even if the progress bar is completely filled, the GUI still shows "Exporting results" but the mosaic files seems untouched since many hours from the beginning of the procedure: I've started the mosaic yesterday at roughly 8 PM, now it's 1 PM the day after and the last update to the happened during the night at roughly 1 AM with no updates since then.

Is there any way to understand if the process is still running or hanged? If so, what could cause this behaviour?
