Jens Geyer commented on THRIFT-3289:
------------------------------------
Not sure, but I remember seeing this behaviour when a large number of sockets
are opened and closed very quickly. The sysinternals TCPView showed very
clearly that the sockets are transitioning into (IIRC) a [TIMED_WAIT state for
some time|https://support.microsoft.com/en-us/kb/137984]. I modified the
application logic in a way that stopped opening and closing lots of of sockets
in a short time frame, and that solved the issue for me.
If you have a better solution, well ... [this is open
source|http://thrift.apache.org/docs/HowToContribute] :-)

> Key: THRIFT-3289
> URL: https://issues.apache.org/jira/browse/THRIFT-3289
> Project: Thrift
> Issue Type: Bug
> Components: C# - Library
> Affects Versions: 0.9.1
> Reporter: Diogo Costa
> Priority: Critical
>
> I'm currently running local load tests between my (local) thrift client and
> local thrift server.
> The test consists of a webpage that makes an RPC call to the thrift server
> using a thrift client and returns the information to the browser. With JMeter
> I'm seeing the performance of both processes under load.
> At some point in the load I get a System.Net.Sockets.SocketException when
> creating a new client with the message "An operation on a socket could not be
> performed because the system lacked sufficient buffer space or because a
> queue was full...".
> I'm using a TServerSocket and a TThreadPoolServer on the server and a new
> instance of TSocket per client request. All instances seem to be disposed
> properly.
> The TSocket doesn't seem to be threadsafe. Am I supposed to create a TSocket
> connection pool in the client so I don't overwhelm the server with creating
> and destroying network sockets?
> Shouldn't there be some connection pooling available in the server
> implementation?
