[Jsonrpc-cpp-devel] Re : Bug report : Accept connexions

Hi,

Thank you. You are right, effectively TCP sockets are not closed prior being removed from the list. This will be fixed asap when I go back home.

Best regards,

Objet : [Jsonrpc-cpp-devel] Bug report : Accept connexions
Date : mar., mars 27, 2012 03:29
Hi all,
Currently working on JSON RPC CPP, TCP Server, I have many concurrent connexions and many many many calls ...
After hundreds of calls, the server took 100% CPU load. The select method did not wait. In fact, the call was registered, but the accept method returned false !

After looking at ERRNO, I found out that I had a too many files opened.
The solution was simple :
Close the client file descriptor after the call to be treated.

In current (non threaded) version 0.4 : File src/json_tcpserver.cpp line 159, close the m_client before removing them from the std::list

I think it is the same for UDP servers ?
For the moment, the file descriptors are never closed .... no a good idea :)

Hope that helps !
