InsiteFX offers a typical setting with session.gc_divisor = 1000 being the recommended "Production Value:. You could make it happen more often with

Code:

session.gc_probability = 1
session.gc_divisor = 500

The ratio of session.gc_probability to session.gc_divisor determines the chance that GC will occur not a hard and fast "once every 500 times".
