`deliver2store.logminer.enable_skip_revise_valid_rowid_exception` 参数的默认值为 false，用于设置是否跳过修正 rowid 引起的异常。 ## 问题原因 OMS 的 Store 组件处理大事务时序列化出现问题（原因未知）。 ## 解决方法 您可以通过设置参数 `deliver2store.logminer.enable_level_store=false`，关闭 Store 组件的大事务处理机制。 请注意，设置该参数会导致内存使用量上涨。必要时请修改 Store 组件的内存配置，以免遇到 GC 问题。 Previous [OMS V3.x 升级至 V4.0.2
