Running some tests on the linkedin hash list, with oclhashcat-Plus4 in brute force mode (3), using --remove and --outfile-format=7, at some points when many hashes are being cracked quickly, I'll see oclHashcat-plus show "<outfile>: Permission denied", then on the next line list one hash:cleartextpw:hexpw.
After a few of these build up over time, Windows reports that oclHashcat-plus64.exe has stopped working.
This is the normal unmasked linkedin list.
Windows 7 64-bit SP1, fully patched.
ATI 13.1 Catalyst drivers, with an HD6950 card.
AMD 1090T Phenom II CPU.
This has been duplicated on both hard drive (all files in the oclHashcat-plus directory) and RAMDisk (IMDisk, likewise with all files in the same directory).
