I would advise exercising caution though. Even if the tool works perfectly fine, the service going down anywhere within days to weeks after you captured its state would be seen by the management as your fault. They won't care for the explanations, they will just need a scapegoat and that would be whoever touched the thing last time.

That said, there are plenty of legitimate (albeit low-probability) reasons for the dumping tool to screw up the service. Slightly affecting memory timing and triggering some rare race condition, using up more RAM than usual (or increasing the HDD utilization) and again triggering some conditions that wouldn't happen normally. You name it.

If it was me, I would try to run the binary on another machine and do a "clean room" recreation of the config file. That said, service without sources and missing configs without backups indicate severe organizational problems, so I would probably not want to work in such a place for a long time, unless I was hired by the CEO specifically to rectify things.
