Reactor Crash - Gauge Explorer

[bf4]

I've finally deployed fnordmetric to our server. After playing around, I started noticing the following behaviour:

When I'm on the "Gauge Explorer" and I select one of the gauges it works fine initially. But, as soon as I select another time range, it starts getting weird.

• goto: [scope]#gauge_explorer
• select a time range from "recent data" (tested it with 24h and 48h, the more you click the worse it gets)
• select the gauge
• As bonus step: reload the page

This causes the following symptoms

• the ruby process is close to 100% CPU
• the ruby process gains more and more memory
• sometimes I had to force kill the ruby process
• redis is at ~ 10% CPU
• page reload takes ages
• when it finally reloads, lots of exception are logged:

[13-02-28 16:34:26] [ERROR] reactor crashed: stack level too deep
/path/to/bundle/ruby/1.9.1/gems/fnordmetric-1.2.6/lib/fnordmetric/gauge_calculations.rb:44

The gauge:

  gauge :sign_ins_per_second, tick: 1.second

Am I doing something completely wrong?
