Not sure what's causing this, but I wonder if it may be related to a high number of threads that may not play well with pprocess. Could you try to run the searchlight with as additional parameter in the call: nproc=1 (disabling multiple processes), and maybe also some other values (e.g. nproc=4 or 8)? Do you know how many threads the searchlight runs with?
