If all of the images have been normalized, then you could just run the melodic command on the list of images. The command should look something like what I have below, but just check your log to get the exact command from your first attempt:
melodic -i .filelist -o groupmelodic.ica -v --nobet --tr=1.58 --report --guireport=report.html --bgimage=${FSLDIR}/data/standard/MNI152_T1_2mm_brain -d 0 --mmthresh=0.5 --Ostats -a concat
I should note that It's not clear whether you ran out of diskspace or RAM/swap... I'm actually thinking you ran out RAM, so see other posts about RAM and group ICA for further guidance.
Cheers,
David

How can I restart this run without having to repeat the timely preprocessing steps, including the warp to standard with 2mm resampling?
