[issue28968] xml rpc server fails with connection reset by peer error no 104
Manish Singh added the comment: Below is the information sent to python-dev group === [ Issue ] I have used xml rpc library with transport as http. My client and server are running on same host. Some xml rpc requests fail with connection reset by peer error number. I have used xmlrpclib.ServerProxy() to call remote method on xml rpc server running on an ephemeral port.

Free up system resources if they are running low. Possibility for 1 and 2 are not applicable as it is loop back communication(Client and Server running on same machine). For Possibility 3, I have already checked system resource and there are enough resources(80% RAM used, 20% cpu usage, around 10 GB RAM free). I checked for other reasons and i found that this issue may be related with GIL, Please refer this link, http://stackoverflow.com/questions/383738/104-connection-reset-by-peer-socket-error-or-when-does-closing-a-socket-resu 1> Can you please let me know, is it really a issue realted with GIL? 2> If yes, How to resolve this issue? 3> If no, what other reason may exists for such failure.

Manish Singh added the comment: Hi Jim, Thank you for replying. As you are suggesting that there is a firewall setting. Then in that case every request should fail, right? But in my case only few request fail(4 out 20 requests).

Manish Singh added the comment: Hi David Murray, Thanks for replying. I have mentioned that my client and server are running on same host. So communication is going through localhost address. I have checked for possible reasons of connection reset by peer error, below are the possible causes, 1) The machine is connected to the network, and the network is not responsive. 2) The other side of the connection is not running normally. 3) There are not enough system resources available. Free up system resources if they are running low. Possibility for 1 and 2 are not applicable as it is loopback communication.
