<br>Dear Paolo<br><br>You were right, changing the number of processors has worked, no matter the option of occupations I choose and the length of the vacuum. Even more, trying with the same script than before, the same numbers of processors, the same machine, etc. has worked. Thus, I guess there is not any real problem and that the machines where I sent the scripts were having some kind of problem those days and have been fixed, I should ask. Sorry for that and thank you very much for your help <br>
