<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt'>I’m
using twisted to build a process management tool. I have a TCP server
that runs reactor.spawnProcess(), it runs the process, but then generates this
stack trace. I’m at a bit of a loss as to how to resolve this..
Is there perhaps another approach I should try? I need to manage long
running processes on remote boxes.</span></font></p>
