Seems from what vi_ and jedi have said, you've posted about this already. That is _not_ good behaviour. If you don't get the help you want from the question you ask, re-phrase it. If you've been waiting a while, by all means bump the thread. The nature of the problem will determine the urgency e.g. device still in reboot loop after taking the battery out and putting back in, as well as expecting a call about a new job - ok, repost in an hour. But don't start a new thread just because you didn't get a reply. The only caviat might be that there are occasions where you will post at the end of an old/dead thread and get a lacklustre response, in these cases starting a new thread might be more appropriate because you can ask the question more precisely to your needs. Whatever you do: Use TMO with care: it's fragile. Not sure it's wise to reward this sort of thing but publishing your findings will probably help others ... lets see what can be done: What version of busy box are you running? What are you trying to execute with 'exec'?
