问题描述
- 当 ONTAP 集群处于混合版本时，节点 mgwd 进程在升级/降级期间意外重新启动，并出现以下错误：
The management gateway server restarted. Waiting to see if the connection can be reestablished.
[Node-01:spm.mgwd.process.exit:EMERGENCY]: Management Gateway (mgwd) subsystem with ID 22443 exited as a result of signal signal 11. The subsystem will attempt to restart.
- 它通过以下消息生成 ucore：
mgwd: Received SIGSEGV (Signal 11) at RIP 0x815aabcdc accessing address 0x98 (pid 22443, uid 0, timestamp 1751871269)
