FahCore21.exe Crashing After Upload

Posted: Sat May 06, 2017 6:51 pm

I appear to be having a recurring issue with Core 21 crashing immediately after upload. I am currently using 378.92 drivers.

It appears that the WU uploads then the core crashes. Windows makes me acknowledge the crashed program via a text box before it reports as failed within the FAH Client.

The failure has nothing to do with the upload. WU02 finished an uploaded successfully and "Cleaning up" seems to have worked correctly. WU01 was downloaded and FahCore_21 was started and then failed. I really doubt there was any interaction between the processing of WU02 and WU01.

Did the client restart WU01 successfully or was it dumped? (after the message 18:28:38:WARNING:WU01:FS01:FahCore returned: FAILED_1 (0 = 0x0))

The Windows exception code 0xc0000374 indicates a heap corruption - to determine the solution, you would need to debug the crash in a debugger to figure out who is corrupting the heap. Heap corruption can also occur spontaneously on overclocked systems.

I wonder if it's something to do with this being a very quick system - the core finishes and starts a new WU in less than a second. I normally have a delay of a few seconds. Only a guess, but maybe something isn't being cleared out fully before the core is fired up again? Anti virus still scanning the fresh WU?

I've encountered this problem as well in the past while running Windows. I would have been running a different version of the video drivers at the time.

Here is the thread that I started: viewtopic.php?f=19&t=28709

Speculation at the time was hardware problem. I believe that speculation was wrong.

All of the symptoms I noticed are described by the original poster:

1) Previous core finishes correctly
2) New core crashes on startup following upload/download.
3) Windows indicates heap corruption problem.

RWH's speculation about a timing related bug makes sense to me ... there is some bug related to one core finishing and a new core starting up that causes heap corruption. It's intermittent and timing related. There are now two instances of this happening. I'm just spit balling here, but thought I'd share my recollection that this particular problem has occurred previously.

I can't think of a relationship between closing one core and cleaning up the files of one WU and starting another copy of the (same or different) core on another WU that would corrupt the heap. Those events happen regularly for people who run more than one GPU though rarely at "exactly" the same time.

(Just because I think there's no relationship doesn't prove anything. If I happen to be wrong, somebody is going to have to figure out how to gather enough information for development to identify the problem. In the passage I quoted above, it says "you would need to debug the crash in a debugger to figure out who is corrupting the heap.")

The fact that Windows provides a popup that must be responded to before continuing means that it has temporarily preserved a lot of useful information that could be of help but somebody would need to produce a mini-dump of that task BEFORE closing that popup. Can somebody do that for us?

Nothing restarted after it crashed.

I'm not incredibly technical but next time it comes up I will go with the option that says debug. I'll play around with Visual Studio and see if I can get anything useful to post here.

It happens once every few days, so I should be expecting another one pretty soon. CPU isn't OC'ed, the 3 GPU (1080 Ti/1080 Ti/1070) in the system have a slight OC (+80/+80).

The second WU crashing during the first WUs clean up may just be a coincidence. However, it is possible that the core is accessing the GPU driver during clean up and that is causing the crash. This would be easy to test. Run a core 0x21 on a WU as normal. Then see if you can crash it simply by running another instance of the core manually. You could run it like this:

Good to know. Nothing has happened yet.

This probably isn't much help.

I couldn't get the call stack on that past error.

Got this error also once, upload succeeded but the fahcore_21 error popup occured. When I click close then a new FahCore_21 is started successfully.

Only error message in log is
17:02:14:WARNING:WU02:FS01:FahCore returned: FAILED_3 (255 = 0xff)

@foldy:
It really has nothing to do with the upload. This message is identified as coming from :WU02:FS01: so looking only at those messages allows me to exclude unrelated messages. Nevertheless, FAHCoreWrapper.exe and FahCore_21.exe attempt to start, fail, reattempt to start, and succeed. I've never seen that before ... and the error message isn't particularly helpful.

Was there anything in the Windows Event log at that same time?

Did you try the test recommended by jcoffland a few posts above mine?

@jcoffland
is FAHCoreWrapper re-entrant?

I tried jcoffland's test but that did not hurt FAH.

I got this error message in Windows Event Log: FahCore_21.exe: 0xC0000374

Looks similar to:
