The Entuity server continually uses and releases sockets, for example when running prole and fpprole. Once released, these sockets only become free again after a time-out period. When running the Entuity server in a Windows environment and monitoring large networks, Windows' default maximum number of user ports may be reached - without available sockets, Entuity performance will be severely impacted. For example, the creation of new prole and fpprole processes will be prevented, and so data collection becomes unreliable.
When using Windows, Entuity recommends that the registry key value MaxUserPort is set to 0x000fffe (65534). Define the new key value as:
- Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
- Type: REG_DWORD
- Value: 0x000fffe (65534)
Entuity configure checks that the server machine has MaxUserPort set. When it is not set, or is set to a lower value than Entuity recommends, a warning message is given, but Configuration can continue past the warning.
