问题描述

系统变得缓慢和无响应。
NAS共享可能不可用。
EMS日志显示以下崩溃字符串：

mgwd: assertion (0) at src/rdb/TM.cc:3838 failed, raising SIGABRT(6) at RIP 0x81d714d9a (pid 2720, uid 0, timestamp 1667352600)

聚合可能会显示为未知状态、但仍会保持联机并提供数据。
高级命令 cluster ring show 可能会显示与节点通信超时/失败：

Warning: Unable to list entries on node cluster-01. Timeout: Operation "cluster_ring_iterator::next_imp()" took longer than 25 seconds to complete [from mgwd on node "cluster-01" (VSID: -1) to mgwd at 169.254.1.123] Error: show failed: Timeout: Operation "cluster_ring_iterator::next_imp()" took longer than 25 seconds to complete [from mgwd on node "cluster-01" (VSID: -1) to mgwd at 169.254.1.123]
