This means the program is segmentation fault at 0x081953f7.
If you run scrun with debug option
    % scrun -nodes=100,debug ...
and your X server can access snowdon.leeds.ac.uk:25.0 from the compute hosts,
gdb is excuted at the time.

If X server dose not access from the compute host,
please unexport DISPLAY environment variable, and scrun with debug optiion.
So you can get backtrace where the program is segmentation fault.
