Add Raster to Mosaic Dataset fails if adding too many files

Question

Hi

I am adding some Rasters (aerial photography images) to a newly created Mosaic dataset.  There are many images (approx 1400).  If I add a bunch of aerials from file to add to the mosaic dataset it fails if I add too many at once.  In my DEV environment if I add more than 9 rasters at once it fails. This is pretty annoying as I have many to add. On my Prod environment I can generally add more but it still fails if I try to add too many at once.    The errors is not particular helpful.  I have tried to use the Input data as a folder rather than a file but that fails as well.

ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.

Thanks all.  I am using my production environment so I wouldn't have thought memory would be the issue.  Also I am adding tiles that are close together.  Also I have the issue with ECW's or JPGS.  If anyone has any other ideas that would be great.  Thanks very much.  Else it will be a very slow process!

Have not tested with ECW's, but have loaded 1400 jpegs, jp2's, and tiff's into mosaics without issue.

I set the Input Data to Workspace and let it grab all the images in there rather than adding them all to the list individually.

Most likely you are running out of memory while the new imagery is being integrated into the mosaic.  If you checked your DEV environment, you will probably find it has 1/2 the memory of your production environment (especially if they used a default VM to create the server with 8 GB memory). Second thing to think about is how you are loading the new images, are they adjacent to each other or are you loading them 'randomly' over the mosaic area. Why? If you load 9 adjacent images, then then we only need to load the tiles that overlap the new imagery to update them. Otherwise, we may need to load the entire set (e.g., if you loaded one new image at the bottom left and another on the top right of your mosaic then the entire mosaic will need to be read at some point to update the mosaic).
