The standard 500 error message (with 404 not found)

The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [external links are visible to admins only] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
But I have the file at:
[external links are visible to admins only] , and at 666
If I change sitemap.html to 644, I can see it
( [external links are visible to admins only] )
but as soon as I run CRAWL again, it changes sitemap.html to 644
