VPHOT error when trying to open image or stacking

General Technical Support

I get the following error when I try to stack images or open an image in

VPhot.

System.OutOfMemoryException’ was thrown

2

VPHOT has been having a lot of little problems for about 4 days now. I have not seen anything repeatable enough to report it. I think it is being choked with too much load.

It seems to be working ok at the present. I just stacked several groups of images.

To those who are experiencing this error: if you haven’t already, you might want to send an email to aavso@aavso.org, which will bring this to the attention of AAVSO staff. To help them debug, I would suggest including a link to this thread, and attaching one of the images which triggers the error.

(P.S.: I merged a couple of different threads into this one, so that all of these related error messages can be viewed in one location.)

In my case it seems to be related to how much activity there is on the service. I tried it last nite and kept getting the error. I tried today and was able to stack all the series of images. There were currently no images in the que waiting for upload.
