SysOrb agent stops checking in from a windows server with very long system uptime


On a Windows server with a very high system uptime(around 500+ days) the SysOrb agent suddenly stops checking in to the SysOrb server.

In the SysOrb agent log you see the following:

Reason given: "Error connecting: An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full. (10055)"

If you run a netstat on the server you get a very long list of TCP connections with the status "TIME_WAIT"


The root cause for this lies in the windows OS please relate to this Microsoft knowledge base article


The recommended solution is to install all latest patches as is likely that hotfix is already present in one of them.
A simple reboot of the server will also clear all the time wait connections and the agent will start checking in again.
