Question mprime does partially idle after some time

I'm running mrpime in it's most recent version on Linux 64bit on a 48 node cluster.

Usually the load of these machines corresponds to the number of CPUs, as they don't do much work (apart from mprime).
After some time however this drops, and mprime doesn't use all cores.
It seems that it never gets back using the other cores, except I restart mprime, then it uses all cores again.

What's the problem here?

Default Mprime dropping cores

Since mprime always starts using all cores, I suspect fatal errors... Fatal errors would be recorded in the result.txt file.

Thanks. You were actually right,... it seems that the problem came from missing write-permission to worktodo.txt :-)

Best wishes,
