High Memory consumption

[jeremysze]

I was attempting to use the rollmatch() function with a lookback of 2. And there appears to be a tremendous memory consumption - from 6gb used to maxing out the 32 gb that I have.

The rollmatch() works when I use a lookback of 1 and the reduce_data from the lookback of 1. I am thinking it might have something to do with the number of observations?

I have 127713 observations in the reduce_data with a lookback of 1 and 224509 observation with a lookback of 2.

It seems like there might be a bug somewhere.
