I have a theory that since this runs every 20 seconds that it is falling behind somehow. Ulimits is too low, twisted is maybe eating the too many file handles exception and then trying to close a handle that doesn't actually exist. Dunno.

We recently switched from these versions and recently our TLS health check using treq seems to be using more and more file handles and getting this exception. Additionally our health check gets response time outs at a much higher frequency. Any tips on how I would go about debugging this? Or is this perhaps a known issue in one of the versions below and I need to either bump up or down a release version? Thanks!
