VerifiedPersistent memory faces issues such as Memory Pollution or Knowledge Drift, with risks including conflicts between outdated and new information, reinforcement of erroneous experience, and degraded retrieval accuracy due to memory bloat77% similarUnverifiedWhen multiple agents share the same long-term context, erroneous memories and information that should not be shared are amplified together, forming a positive feedback loop of memory contamination.75% similarUnverifiedMemory drift is an easily overlooked failure mode in long-running agents, where early misjudgments can become premises for subsequent inferences, forming erroneous self-reinforcing loops.73% similarUnverifiedMemory plugins act across all sessions; once written content is erroneous, summaries lose focus, or retrieval hits hallucinated content, the contamination continues to spread into subsequent tasks, and it is not accompanied by explicit errors.71% similarUnverified在多智能体共享记忆场景下，错误经验可能被其他智能体在不同场景下错误引用，形成级联错误，即「经验污染」70% similar
