Marcus, It would be useful it you could provide a gdb stack trace of all threads when you see the "wedged condition". If it's a python program, run gdb against /usr/bin/python and use the gdb attach command to attached to the wedged process. Then issue thread apply all bt to generate the stack traces and send them to me.
