Upload Issue with Wide Images

Currently running v3.0.1 and recently move hosting from GoDaddy to Host Gator. The issue is the image upload and resizing is not working for wide images. Media setting for images is set at max 600px. It does not appear to be tied to the image size but the width of the image.

Example 1 – 5500px wide images that is 9mb in size will not upload correctly and create the different size images. The image get uploaded via the browsers upload process and goes to a “white screen”. When I return to the media files the very large image is shown but it can not be edited within WordPress. Limited information about the image is shown in the editor. No smaller sizes (large/medium or thumbnail are created.) If I try to upload using the Flash Upload process when it starts the “crunching” process it returns a message “HTTP Error.” If I re-size to 3000px wides and it is 4mb in size it will upload and create the three different size image (large/medium/thumbnail).

Example 2 – 5000px wide image that is 475kb in size will not upload correctly and create the different size images. The image get uploaded via the browsers upload process and goes to a “white screen”. When I return to the media files the very large image is shown but it can not be edited within WordPress. Limited information about the image is shown in the editor. No smaller sizes (large/medium or thumbnail are created.) If I try to upload using the Flash Upload process when it starts the “crunching” process it returns a message “HTTP Error.” If I re-size to 3000px wides and it is 270kk in size it will upload and create the three different size image (large/medium/thumbnail).

When this same site was running on GoDaddy (same WP version, same theme and same plug-ins) I did not have this issue.

I have talked to three different people at Host Gator with no solution. One tech was reviewing log files following the uploads and could see no errors or issues.

Please offer suggestions / solutions. Thanks.
