This document explains why RSI captured on PTX device with large route scale may become huge in size and may contain all routing table entries within the RSI. 

RSI is more than 3.7 GB

There is a difference in RSI in affected version where it takes output of "show route" which causes issue, when router has BGP routes(almost 1 million routes).

cat LAB_RE0_rsi  | grep "show route"
LAB_RE0> show route summary
LAB_RE0> show route forwarding-table summary
LAB_RE0> show route
LAB_RE0> show route forwarding-table all

The CLI command output of "show system processes extensive" should not have an 'srd' entry on PTX. If it does have, the RSI collection will include the entire  'show route ...' hierarchy causing the dump to explode in size when the route scale is in millions
