WSAENOBUFS: No buffer space available

[former_member182675]

Hi to all

I need youradviseplease

We have EWM system connected to external system withsqlserver and .net connector

Nowevrytime we have themicrosoftevent 4227

TCP/IP failed to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint. This error typically occurs when outgoing connections are opened and closed at a high rate, causing all available local ports to be used and forcing TCP/IP to reuse a local port for an outgoing connection. To minimize the risk of data corruption, the TCP/IP standard requires a minimum time period to elapse between successive connections from a given local endpoint to a given remote endpoint.

andin the logs of the .net connector I have the error

2015-11-08 16:29:48.879 [Thread 4] RfcDestination.GetClient threw RfcCommunicationException:

I openedincidentto sap andmicrosoftand all therecommendationdidn't help me. (changeparameter of the registry MaxUserPort,  TcpTimedWaitDelay)

wetry to upgrade the .net connector to version 3.0.16 but it didn't help

I need youradvise.

Maybeitsa problem in the configuration of the .net connector

PoolSize>50</PoolSize>

   <PeakConnectionsLimit>100</PeakConnectionsLimit>

   <ConnectionIdleTimeout>150</ConnectionIdleTimeout>

   <IdleCheckTime>60</IdleCheckTime>

maybeit'sproblemin the code weusingin the .net connector

doyou have any idea?

Thanks
