random error codes after implementing memcache

I am using google app engine with python and I just implemented memcache and everything looks good on the user side. The data is being cached properly but when I look into the logs I see random error codes popping up each time I open a page. Now they are the same for a single page no matter how many times I open it and it is only being stored in memcache one time but two error codes come up each time. The first one is always -1 and the second is random. Some examples are 194, 214, 204, 77, 208, and 158. There is no more information besides the time.

Here is my code that is doing the actual caching and this happens every time a user puts a new post on my website:

class PostPage(BlogHandler):
    def get(self, post_id, subject):
        key = db.Key.from_path('Post', int(post_id), parent=blog_key())
        key = str(key)
        post = memcache.get(key)
        if post is None:
            logging.error('DB QUERY')
            post = db.get(key)
            memcache.set(key, post)
        if not post:
            self.error(404)
            return
        self.render("permalink.html", post = post)

Any idea what could be causing this? Is it my call to get Key.from_path?

Here is the actual log:

I don't think those are (real) errors, something is logging those numbers with log.error, look for log.error('%d' (or log.error('%s' ) in your code. possibly in your render() method.
