--- I AM getting a .vel and a .coor file for abnormal termination of a
simulation (I checked that again by forcibly killing one).

---- I do not have the binaryrestart option in my input file (hence yes by
default), but I do NOT get any namdbin file!!
Could you please point out what's going on? I am using NAMD 2.6.
