Symptoms

SRM 收集器无法成功启动。

从 SRM 3.7.x 升级到 SRM 版本 4.0.3 时，可能会出现此问题，

并在 4.1 继续。NetApp 收集器每隔几天停止一次。NetApp 收集器日志显示以下错误： 
WARNING -- [2017-05-22 10:06:37 CDT] -- RemoteCLICommandExecutor::getConnectionResults(): Connection result couldn't be retrieved.
java.util.concurrent.ExecutionException: java.io.IOException: com.watch4net.apg.ssh.api.exception.SSHException: com.jcraft.jsch.JSchException: Session.connect: java.io.IOException: java.net.BindException: Address already in use (Bind failed)

运行命令 ps  ef | grep 22 在有问题的收集器主机上。NetApp 收集器使用端口 22 与 NetApp 设备进行通信。在这种情况下，共有 1322 个 TCP 连接 FIN_WAIT1: 
artoxxxxx-col:~ # netstat -ano | grep 22
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      off (0.00/0/0)

tcp        0  61369 xxx.xxx.xxx:59959    xxx.xxx.xxx.xxx:2010     FIN_WAIT1   unkn-4 (82.22/0/0)

Cause

TCP 连接的数量会不断增长，直至达到限制，并阻止收集器建立新的 TCP 连接以与其他设备通信。

Resolution

必须在主后端重置防火墙以解决此问题。

  1. 通过 SSH 连接到主后端服务器，然后运行以下两个命令：
/sbin/SuSEfirewall2 off

/sbin/SuSEfirewall2  on
  1. 完成后，通过 SSH 连接到 NetApp 收集器主机并运行以下命令（ FIN_WAIT1 不应再看到连接）：
artxxxxxxx-col:~ # netstat -ano | grep 22
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      off (0.00/0/0)
