[Sui Foundation Releases Analysis Report on Three Mainnet Outages: Two Independent Bugs Introduced in v1.72 Upgrade] BlockBeats News, June 1 — The Sui Foundation has released an analysis report on the recent three mainnet outages, attributing the incidents that occurred last Thursday and Friday to two independent bugs introduced in the v1.72 upgrade. The first outage lasted approximately six and a half hours, while the second and third outages occurred on Friday morning and afternoon, respectively. The first two outages were caused by a flaw in the "address balance" feature introduced in v1.72, which exposed a defect in the transaction fee deduction mechanism. When transactions were canceled due to insufficient funds, the network still deducted those funds, resulting in negative balances that caused validator nodes to crash during reconciliation. The foundation acknowledged that the emergency patch pushed on Thursday carried known risks of further outages, but the team accepted these risks to quickly restore on-chain services. This led to another outage on Friday morning. The third outage was triggered by another undisclosed random state bug, which occurred when validator nodes restarted to install the patch. Sui stated that user funds were never at risk, both bugs have been fixed, and a mechanism to forcibly terminate stalled epochs has been established. [Original Link]
