Description benapetr 2014-11-28 11:29:40 UTC
I have this code:

                            Process proc = new Process
                            {
                                StartInfo = new ProcessStartInfo
                                {
                                    FileName = ts.task.Path,
                                    Arguments = ts.parameters,
                                    UseShellExecute = false,
                                    RedirectStandardOutput = true,
                                    RedirectStandardError = true,
                                    CreateNoWindow = true
                                }
                            };

                            proc.Start();
                            while (!proc.StandardOutput.EndOfStream || !proc.StandardError.EndOfStream)
                            {
                                string line;
                                if (!proc.StandardOutput.EndOfStream)
                                    line = proc.StandardOutput.ReadLine();
                                else
                                    line = proc.StandardError.ReadLine();
                                if (ts.channel == null)
                                    IRC.DeliverMessage(line, ts.user);
                                else
                                    IRC.DeliverMessage(line, ts.channel);
                            }
                            proc.Close();
                            proc.Dispose();

It does in most cases create a new process, which finish and then remain as a zombie. Is this a bug in mono, or do I miss something to clean up? Happens on linux only.
