The first two likely cause the third, so I'll focus on them; exit code
124 is a timeout error, meaning Indigo had to give up waiting for a process to start. The problem is how to identify what process 82,929 was (it's quit by the time you get the error), and then work out what might be causing it to time out.
I've just extended the error so that it lists the command that was running at that PID, so in the next release this should be more helpful.
Thanks for emailing through the logs — I'll get back to you via email.
