Problem of running I-TASSER --- Continued

Dear, I finish running the last step for the I-TASSER, here is the result:
-libdir =/home/rcrg4/class_project/tool/I-TASSER
-seqname =seq.fasta
-datadir =/home/rcrg4/class_project/tool/I-TASSER/data
-usrname =rcrg4
-runstyle =parallel
-homoflag =real
-idcut =1
-ntemp =20
-nmodel =5

and it did the simulation parrallel , then it did not work anymore, the process was not running anymore. What's that problem? Does that mean my computer has not enough space?
And I try to kill the process, but after that, I find another problem, see:
./runI-TASSER.pl -libdir /home/rcrg4/class_project/tool/I-TASSER -seqname seq.fasta -datadir /home/rcrg4/class_project/tool/I-TASSER/data -usrname rcrg4 -runstyle parallel
and
[2]+ Done ./runI-TASSER.pl -libdir /home/rcrg4/class_project/tool/I-TASSER -seqname seq.fasta -datadir /home/rcrg4/class_project/tool/I-TASSER/data -usrname rcrg4 -runstyle parallel
It will finish immediately, should I delete some of the results for last running?
Thank you very much!
