Some counter trigger error in event logs

[pkolmann]

Since upgrading from 0.5.8 to 0.5.14 I see a lot of errors in event log and it seems some counters trigger this.

If I only specify one counter, the problem doesn't surface, but with the attached WindowsPerformanceCounter.config I see a lot of these errors in the Event Log:

ReadThreadProc() got exception : System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list. at System.Text.StringBuilder.AppendFormat(IFormatProvider provider, String format, Object[] args) at System.String.Format(IFormatProvider provider, String format, Object[] args) at BloombergFLP.CollectdWin.PerformanceCounterMetricGenerator.NextValues() at BloombergFLP.CollectdWin.WindowsPerformanceCounterPlugin.Read() at BloombergFLP.CollectdWin.MetricsCollector.ReadThreadProc(), at System.Text.StringBuilder.AppendFormat(IFormatProvider provider, String format, Object[] args) at System.String.Format(IFormatProvider provider, String format, Object[] args) at BloombergFLP.CollectdWin.PerformanceCounterMetricGenerator.NextValues() at BloombergFLP.CollectdWin.WindowsPerformanceCounterPlugin.Read() at BloombergFLP.CollectdWin.MetricsCollector.ReadThreadProc()

The first few minutes I still get values but after some time, I don't get any output anymore.
