Came across a strange issue

Running SHA1 combo attack with a small left list and a large right list

3/4 of the way through it froze. System didn't freeze but the process oclhashcat process did.

GPUs were not at full load since it was tuned to 8 from 80 as there wasn't enough work from the left list.

There is the spot it has frozen at.
Drivers: 13.4
Cards: 7970 + 5850

I know it's a bit vague but will post again if the issue arises again.

Is this reproducable? Does it freeze every time at the same spot? Else I'll go ahead and claim defective hardware/overheating problem.

I noted the same behavior, with same drivers, cards 2 x 6990.
Not a problem with 016.b53, but the recent 0.15 and 0.16b72, b73
and b82 have the same behavior.
Didn't report as it could be a problem from my own side, hardware
or something else... Now that I see blazer report...
Didn't tested SHA1, but noted immediately with MD5.

Same problem described happened to me.

OS 7 x64
5850 + 5770
Cat 13.8 beta v1

OCLhc 0.15 stable

Attack -a 0 + best64

Hashset: ~1000 hashes.

there is beta2 up, try again please

Beta2, cat 13.4
After this crash, running the same command line once, no error (at least, when trying one more time).
Using a folder with multiple dictionaires freezes again or crash.

I get this (oclhashcat64.exe has stopped working) often too. It seems to me that it's almost always near the end of an attack. I get also the following error: clenqueuewritebuffer() -30

In my case it was in windows7 64bit catalyst 13.8beta and on oclhashcat version 1.00b3.

those threading semaphores gave us some headaches. try new beta4 please

Looks like the crashes are solved. When my attacks will finish, I will test the freezes on bruteforce/mask attacks.

@mastercracker please have also a look at my comment in https://hashcat.net/trac/ticket/82 , I think those changes we made recently fixed that problem (too)

Can you please run the exact same commands (w/ bat and/or hcmask) and close the ticket if it was fixed?

Thx
