Cause

通过 snmpd 轮询 IPStorage 接口收发器的内存泄漏

Resolution

解决方法:
要防止 signal 6 crash,监控 SNMP 服务内存使用情况,并在 MemUsed 达到 MemLimit 的 90% 之前,无中断地为结构交换机和控制器级交换机重新加载交换机和系统切换:

show processes memory | include "PID|snmpd"

控制器交换机: system switchover 
光纤交换机: reload system non-disruptive 

SNMP 服务会在系统停止后自动重新启动,并且不会中断。

修复:
升级到 NX-OS 9.4.4
