[rrd-users] Limits on the number of DEFS in rrdxport

I've built the beginnings of a simple tool that lets you specify rrd
aggregation 'recipes' using regular expressions on the paths to rrd files
. So suppose you have data for N nodes in the following directory
structure, where the first two letters refer to a location:
Then you could aggregate the data for all possible locations using this
Rather than building a new processor, I leveraged rrdxport's nice
aggregation interface. In other words, recipes in yaml format are converted
into invocations of rrdxport.
*This works fine, except when the number of DEFS in rrdxport exceeds a
certain number. At that point, rrdxport simply returns without giving any
Is there a limit on the number of DEFS you can pass in a single rrdxport
invocation, and if so then is there a way of raising the limit?
This is the version of rrdtool that I am using:
