Hi Marco,
I can't think of anything that would cause this, and we haven't had other reports of it happening. Ferret makes a Fortran "system" call,
https://gcc.gnu.org/onlinedocs/gfortran/SYSTEM.html
and does nothing more, so there's not much to it. If you start Ferret with "ferret -secure", where system calls are not allowed, then you'd see an error message, but it doesn't sound like that's the case.

Dear Ferretters,
Sometimes the spawn command doesn't work anymore, so usually
yes? sp echo test

but sometimes
yes? sp echo test
The same for any other command I tried. After restarting Ferret
spawning works again. I do not know how to reproduce this. Any ideas
why this may happen?
I'm using Ferret 6.93 (on RHEL/CentOS 6.7).
