We use it since  Junos 14.2. No bug encountered related to this feature.

It depends on your sizing. As Tim said check the RPD memory - Just never reach the 80%.

64bit RPD is newer, and by nature will have more bugs - so don't run this
unless you need it. Check this with "show task memory" - this will show
what you have used of the RPD accessible memory. As Phil notes, you'd need
significant RIB scale (which does exist in larger networks) to require

Enabling this will cause RPD to restart as you kill one process and start
