Networker on Windows - EventID 4227
Hi,
how to solve this EventID?
EventID 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.
NetWorker 7.6.4.1.Build.1049 on Windows 2008 R2
thank you

The problem is not application in my view, but more port allocation/TCP issue.

yes but this port allocation make Networker so maybe Networker use TCP ports incorrectly..

I would argue that in any system port is allocated by OS service as per preferred range which may be bordered by application settings. Did you try 7.6.4.2 by any chance? I'm not using it on Windows platform, but I recently went to it and it is way better that 7.6.3.7 I was using before. Since you believe this might be caused solely by application, try 7.6.4.2 patch release.

Had the same isse after update from 7.6.1 to 7.6.4.3. Every two days the server needs a reboot because networker was not able to establish RPC calls to clients and himself. I expanded the TCP hash talbe to 1024 like described in this MS article. This solved my TCP errors in Eventlog and NetWorker is now running stable.
