I can't say if thistem is *the one*. I usual have those problems when I add some echo into a script for debugging and depending how many echo's I added, possibly where, how close they are together (or not ?), I most definitely loose some of them. Usually when that happenes, I will be loosing always the same ones. However, since the debugged script has a tendency to change quite quickly, the problems will or not move with changes. So, in some sense maybe my problem is not strcitly speaking the same as that of the original poster since it is not realted to any mapping, rather a straightforward exec of echo inside a script. ---Zdenek
