Ephemeral Port Exhaustion

Overview

There is a problem in SAM port monitors where they go intermittently unknown.

Environment

All versions of SAM

Cause 

Error found in C:\ProgramData\Solarwinds\Collector\Logs

Collector.businesslayer.log:

 

 

2013-07-23 07:31:21,331 [44] FATAL SolarWinds.Orion.Core.Common.RemoteFeatureManager - Unable to load Feature Manager data from SWIS

System.InsufficientMemoryException: Insufficient winsock resources available to complete socket connection initiation. ---> System.Net.Sockets.SocketException: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full 10.95.8.107:17777

 

You can also verify the issue via running the following command from the command prompt:

 

Netstat -aon

 

The output of said command will show you the port utilization.  The expected result is that they have page upon page of ports that are in a TimeWait or a CloseWait state.

Resolution

Please following the instructions on the following Mind Touch article:
