WRITING EXTENDED SYSTEM TO RESTART FILE AT STEP 46996000
WRITING COORDINATES TO DCD FILE ionized_run2.dcd AT STEP 46996000
FATAL ERROR: seek failed while writing DCD file: No such file or directory

The file is there in the correct directory. I restarted the job and it
appears to be running again quite happily.

I'm running Windows 7 64 bit; reading/writing to a local drive;
"NAMD_2.10_Win64-multicore/namd2 +p4 namdrun.conf" is the command I
used.
