Builders beforehand traced the incident to a “crash bug within the fuel filling logic launched within the 1.72 launch.” Whereas validators have since patched their techniques and resumed operations, this stall as soon as once more highlights ongoing dangers concerning scalability and validator coordination.
Validator hangs whereas RPC node stays on-line
