SRVO-188: Memory is lacking

Payload Estimation couldn't allocate enough DRAM to run.

What it means

Payload Estimation couldn't allocate enough DRAM to run.

Common causes

Ranked by what technicians most often find, most likely first.

  1. Insufficient free DRAM at estimation time.
  2. System genuinely under-membered for the option set.

How to fix it

  1. Re-run after a power cycle, which frees memory.
  2. If it persists, the controller needs a DRAM size update - document and contact FANUC.
