If PectAgent is crashing, it generally exits. That's what a crash is.
Are you still seeing this? It's been a few days. If so, I have a few more questions.
1) what is the first task in the job? Is it imaging, or a script of some kind?
2) what version of DS are you using? 7.1? 7.1 SP1? 7.0? and at what MR release if applicable?
3) what if you re-launch the PectAgent, at this point it's now in the console, and you run the same job/task against a now "known" computer - does that work?
As for manually selecting the task to reboot to automation - that's by design - a design we hope to change, but no promises. If you're comparing against 6.9 that did it for you, you're right, the "automatic" part of that is now missing, but it was missing on purpose.
