Hello, That makes sense, and I was pretty sure that just creating a new isolate was clearly not the way to go. Since I'm dealing with Persistent objects, what should I do, then? I read somewhere that if Isolate::GetCurrent() returned NULL, it was because the current isolate was being already used, I guess by the running node.js itself?
If so, I really need assistance, because I technically can't stop it (because other modules are running on it and some are time-sensitive), and even if I could, I don't see how I'd do that. I can't test your suggestions right now but will try tomorrow and make a follow-up. Thanks a lot!
