Dogstatsd aggregator is complaining about empty values

[AndreBremer]

I am seeing lots of these in the dogstatsd log.

uwsgi --connect-and-read shows data (although lots 0 values)

Suggestions?

Hello @AndreBremer, would you mind sending some information about the system which runs uwsgi?

ldd `which uwsgi`

or

otool -L `which uwsgi` # in case of osx

Sure thing!

@AndreBremer looks like 46c7d5f25e3b86c6fe00aaa4f24064d3abe5640c should fix the bug. Would you mind pulling master and confirm before I close the issue?

[AndreBremer]

Looking great! Thanks for the quick response and fix.
