VASP hangs after NELM or LABORT

Why would VASP hang after completing NELM electronic loops or receiving a hard stop (LABORT)?

I'm running a 128 atom cell with hybrid functionals (HSE06) and trying to calculate band structure. However, the cluster (SDSC Comet) has a short queue timeout of 48 hours. The job completes 2-3 electronic steps (to 2E-6) with ICHARG=11 within the first 24 hours, and it will acknowledge either LABORT=.TRUE. in STOPCAR or just NELM=2 in INCAR. But nothing happens after that. It does not write the PROCAR file. I read somewhere that hybrid functionals require self-consistent runs (ICHARG=1), but I've run many band structures with ICHARG=11 so far. Is it just the inclusion of too many k-points?

I'm using ISTART=1; INIWAV=1; ICHARG=11; LHFCALC=.TRUE.; HFSCREEN=0.2; PRECFOCK=Fast; LREAL=.TRUE.
ISMEAR=0; SIGMA=0.05; ALGO=Damped; TIME=0.5; LDIAG=.TRUE.; PREC=Accurate; LPLANE=.TRUE.
NSW=0; NELM=3; IBRION=-1; ENCUT=520; EDIFF=1E-8; LWAVE=.TRUE.; LCHARG=.TRUE.
CHGCAR and WAVECAR were converged to 1E-8 in previous HSE runs. I don't know why dE is so large in this run after being well converged previously.
