Symptoms

从 errdump 输出：

Cause

交换机遇到 FOS-863077 ，此缺陷导致内存泄漏。

症状：
这 weblinker daemon 在 SANnav 监视期间，内存使用量持续增加，并且诸如 configupload 开始失败。

当前交换机版本 Fabric OS 9.2.2 没有该修复。客户正在使用第三方监控工具，该工具也会受到影响。

SRM-5011 错误显示其从 2025 年 7 月 21 日开始达到限制的 75%，因此需要 1 天时间进行故障切换：

2025/07/21-18:19:43:390633 (CST), [SRM-5011], 2330474/0, SLOT 2 | FID 128, INFO, CC-MA001-SANX7-1, phy memory utilization meets or exceeds threshold of 75 percent. Current value is 76 percent., osmisc.c, line: 405, comp:osmiscd, ltime:2025/07/21-18:19:43:390406

可以看到，有很多 LDAP 登录失败消息。由于所有登录失败都来自 HTTPS，因此它们使用 weblinker 进程请求许可证。他们正在耗尽可用的 weblinker 内存耗尽，导致内核崩溃恢复。

Resolution

默认情况下，在第 7 代系统上，流监视器处于启用状态。但是，如果任何运行 FOS v9.1.0 或更高版本的交换机禁用流监控，则可能会出现此问题。此问题也可能在未安装 Flow Vision 许可证的第 6 代平台上公开。

解决方法：
激活流量监控器：

 flow --activate sys_flow_monitor

在没有 Flow Vision 许可证的第 6 代系统上，升级到具有此问题修复的 FOS 版本。

  • FOS9.1.1d6RN-闭合 
  • FOS9.2.0c3RN-关闭 
  • FOS9.2.1bRN-关闭 
  • FOS9.2.2aRN-关闭
