[Mono-list] Different random errors connecting to a service

[Alberto G]

Hi all, I am trying to connect to a vendor  SOAP service and I created a
very basic 7 lines consoleapp that just connect to the service but when
trying to run same .exe several times I get 3 different output errors each
time. Same  application runs ok in windows.

Why for the same application without doing anything different the errors
are so random/different? Looks like execution 1 is almost fine but is
failing to dispose something when application exit.

I can provide SSH access if necessary or provide any additional information
that is necessary. This is running mono 3.12 on ubuntu 14.10.

Source Code:

        static void Main(string[] args)
        {
            var vc = new VimClient();
            Console.WriteLine("Connecting...");
            vc.Connect("server01", CommunicationProtocol.Https, 443);
            var login = vc.Login("root", "xxxx");
            Console.WriteLine("Disconnect");
            vc.Disconnect();
            Console.WriteLine("App_Exit");
        }


Errors:

Debug info from gdb:


=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
