问题描述

数据服务可能会受到影响、从而导致客户端和应用程序挂载失败
Node1的EMS报告EMS和VIFMgr中存在大量与网络相关的错误

Sun Jun 14 23:59:05 -0700 [node1: vifmgr: vifmgr.rpc.nblade.timeouts:error]: The Logical Interface Manager (VIFMgr) is not receiving responses from the nblade.

自此之后、我们每天都会看到这些错误。
最终导致NFS因系统挂起而中断
由于此消息是指VIFMgr、因此我们检查了VIFMgr日志、发现在EMS中出现第一个错误之前、进程已超时。
