Error Removed v138 → v150 (removed) 19.2

The subnet has reached its maximum capacity for neurons.

What This Means

The subnet has reached its maximum capacity for neurons.

Common Causes

  • All UID slots on this subnet are occupied
  • High-demand subnet with many validators competing for slots
  • Registration burst - too many people registering this block

How to Fix

  • Query SubtensorModule.SubnetworkN(netuid) for current count
  • Query SubtensorModule.MaxAllowedUids(netuid) for the limit
  • If SubnetworkN >= MaxAllowedUids, wait for pruning (low-performing neurons get replaced)
  • Try a different subnet with available capacity
