Hello everyone, I am running into troubles with some of my scripts that make use of tk.createfilehandler() to catch the output messages of subprocesses I started with popen2.Popen4() (debian linux, python-2.3.5, tk-8.4.9). Sometimes when those background processes are running it happens that the gui freezes and the processlist shows the subprocess in zombie state. I've been using the same scripts without problems on mandrake (with several versions of python and tk), so I came to think the problem may be the debian build of python / tk. Now I found that on debian (unlike mandrake) tcl/tk is build with --enable-threads, so I thought this *might* be the cause for the problems. I tried and replaced the call to tk.createfilehandler() with a "manual" loop that reads Popen4.fromchild() to catch the output messages and the problems seem to be gone, so it looks like using tk.createfilehandler() with threaded tk is the problem. Does anyone have an idea if this makes sense or am I on the wrong track?
