Very strange ... (1) this could be a problem with the alternate directory logic, which I've never tested - on my dual cpu systems I've just installed twice in seperate directories. On linux this wastes no space since you only need one copy of the executable - by default the program uses workfiles in whichever directory is current when the program is started. Since this includes local.ini - with the Pid line - you can start as many copies of mprime as you like, provided they're in seperate directories - whilst this is useful for testing, there is clearly an efficiency issue if you have more mprimes running than you have CPUs!
(2) there might possibly be an issue if there is a problem writing prime.spl for some reason e.g. the filesystem is temporarily full / user quota exceeded or some similar problem. Try digging in the logfiles, something interesting might turn up. I always run with "InterimFiles=1000000" in prime.ini. If I got a problem like that I would put the assignment back in worktodo.ini & use the savefile from the last million iteration checkpoint (unless I had a later Pnnnnnnn file from a daily backup).
