I've noticed that if you perform large numbers of runs from within a 
single .ctl file under Linux it sometimes eventually runs out of memory. 
I haven't been able to find any memory leak in MPB, so my best guess is 
that there is one in Guile.

A workaround is, when you have simple parameter-sweep loop, to put the 
loop outside MPB (i.e. launch a new MPB process for each loop iteration). 
e.g. in the bash shell under Linux, do:

 	for x in `seq a dx b`; do program x=$x myfile.ctl; done
