It's either a plugin conflict, theme conflict, or PHP memory issue. I would start with increasing your PHP memory as deactivating plugins could mask a PHP memory issue because deactivating plugins will free up memory which would allow it to begin working properly.
But it sounds like the AJAX is unable to fire because of a lack of available PHP memory.
Here is a tutorial that discusses how to increase available PHP memory:

After you do that, if it doesn't work then it could be a conflict. You'd have to check for theme and plugin conflicts by deactivating everything and activating plugins one by one until you encounter one that triggers the issue to start happening. Same goes with your theme, you'd test your theme by testing using the default Twenty Ten theme.
But it sounds like a PHP memory issue.
