One of my JuMP models seem to be too much for Gurobi/Gurobi.jl – after a while, it kills Julia with SIGKILL. Other models of similar structure work just fine; I suspect the reason is that they are smaller, and that I’m running out of memory with the problematic one … is that documented behavior? Does anyone have experience with this?

It does indeed seem like that may be it – and that setting `NodefileStart` could possibly help. I guess I’ll try that.

It could be your operating system killing the process, not the Gurobi solver.

Yeah, that’s my conclusion, too. Just confused myself initially. 🙂

You should look at the `gurobi.log` file for clues. This doesn’t seem like an issue with Julia and JuMP. You could contact Gurobi directly for support.

Yeah. [According to Ed Rothberg](https://groups.google.com/d/msg/gurobi/gOmiJzLlaRw/aaoLwZiu_UQJ) (from Gurobi), a SIGKILL from the OS does indeed generally mean that Gurobi has run out of memory.
