After those 2 runs without problems, I haven't been able to get a world or release to finish again. Always some process that gets stuck somewhere with no error or anything. If I kill it it dies and everything seems ok again. One thing that I have noticed the last few times is that there is always a zombie process when this happens and it looks like it is the zombie's parent that gets stuck. If I kill the parent, the zombie goes away and the rest of the processes that was waiting for it to finish untangle themselves. I have also tried allproc2.diff, but it did not seem to make a difference.
