When using NodefileStart = 0.5 at a certain point ( about a day in) of the optimisation routine the solver gets interrupted with the following error:

Solve interrupted (error code 10019)

GurobiError: Unable to write node file ./grbnodes0/GRBnodefile386525

Does this mean that my hard disk ran out of space? Is there a way around it?

  Hi Giordano,

  Yes this is likely meaning you have run out of disk space.  The docs for NodeFileStart suggest to limit threads:

  If you still exhaust memory after setting the NodefileStart parameter to a small value, you should try limiting the thread count. Each thread in parallel MIP requires a copy of the model, as well as several other large data structures. Reducing the Threads parameter can sometimes significantly reduce memory usage.
