This certainly does not look right. Either there are some
unrelated requests in the log, or requests are not limited as it
can be expected from your configuration. Some additional things
to check:

- Make sure the $host variable you use for the limiting is not
empty and not changed between requests created by your testing
tool. Try logging the variable to see if it changes or not.
Alternatively, replace it with a static string to see if it helps.

- Make sure there are no unrelated requests in the log. In
particular, you may want to use different logs in the server{}
block you are limiting and in the http{} block.

- Try another tool to see if you are able to reproduce the same
effect. Something simple like "ab" or "http_load" might be a
good choice.
