[phenixbb] problem in rosetta rebuilding

Hi i tried to run rosetta on a unix machine (ubuntu 9.04) for my data. Upto MR step everything goes fine , but during the rebuilding step after 20 cycles the computer shuts down. i have attached the log file for the autobuilding run of rosetta. i am using phenix 1.7.1-743 version. i will be grateful if some one helps me out -- INTEKHAB ALAM LABORATORY OF STRUCTURAL BIOINFORMATICS KOREA UNIVERSITY, SEOUL
