Odd 404 messages

[Artisan]

I receive 404 messages when files are not found on some of my clients' hosting accounts, and a v6 Catalog site is apparently not finding 2 class files; EA$COMClassObject.class and Catalog/EABeanInfo.class, on a fairly regular basis. The store seems to work OK but can anyone tell me why these files are being requested and not found?

BTW the full paths for the above are:
