997: Overlapped I/O operation is in progress.

[steww]

Same issue here, I've been having the same error message since I first installed the client about a week ago. The advanced control client keeps going from Connecting -> Updating -> Connected -> Connecting (spending most of its time in "Connecting").

I'm still able to receive work units and get points but the advanced control client keeps reconnecting.

I was also having issues with my browser control refreshing but after using the "F12 + Disable cache" workaround, it's no longer refreshing.

I also have this issue on one of my AMD machines

One with Issue:
Ryzen 5 3600
Rx 570
win 10

One Without:
Ryzen 3 1200

Same here two epyc Rome system affected with that error and connection status change

Two Xeon Machine have no problem

all have no GPU

Do you get the same problem on 7.4.4?

Not sure if this one will work on 10, but it may?

I also got the same issue already described here.

AMD Threadripper 3960X + Nvidia 2080 Ti

7.4.4 doesn't work for me.

More interesting information:

I only get this issue whenever I have a FAHControl connected to my instance attempting to fetch the logs.

Those messages aren't present for the duration that FAHControl isn't open. My temporary workaround is to only open FAHControl to get the logs and then close it again.

You don't need to use FAHControl to get the logs, you can always access them directly as read-only from the working directory.

On my system it is here (Windows 10):
C:\Users\PantherX-H\AppData\Roaming\FAHClient

Just wanted to jump in and add something:

Been running the FAH 7.5.1 Windows client for about a month on two AMD machines (both Ryzen 7 2700X CPUs.) They've worked perfectly fine.

Last night I upgraded one of them to a Ryzen 9 3900X, effectively doubling my processing power, but now I'm getting the "997: Overlapped I/O operation is in progress" error every few seconds on the upgraded machine. Based on some Googling, it does appear that the 3rd gen Ryzens/Threadrippers are susceptible to this. (Ugh.)

I'm glad I'm not the only one having the problem, but I sure hope it gets fixed soon!

This definitely seems to be connected to the Ryzen 3xxx chips. My system's been doing it since I upgraded last night:
Ryzen 9 3900x
AMD 5700XT
Win 10/64 bit
Asrock x470 Tachi motherboard (3.43 BIOS)

I'm pondering upgrading the BIOS to see if that helps. Most recent is 3.90, but "most recent" is how I got into this predicament.

This behavior also happens with AMD Epyc Rome (7002 series) CPUs in Windows 10.

I have some good news to report: I went ahead and upgraded my motherboard BIOS to the latest (3.90) and the problem seems to have disappeared.

System Information:

Ryzen 9 3900X
AMD HD 5700XT video card
ASROCK X470 TaiChi motherboard

To recap, the problem started when I went from Ryzen 7 2700X to the Ryzen 93900X and disappeared with the motherboard BIOS upgrade. So, happy folding!

Thanks for the info Tom, I just did the same and so far so good!

I'm a developer and this in not an error but a status code that shouldn't be logged.

It's an fyi status from Windows saying "ok I acknowledge your request to read some data. There isn't any data in my buffers right now but when I get some I will notify you".

This is normal behaviour when the client reads/processes data faster than the server can send it.

You see in the logs the download does complete successfully, so these messages cause no harm but they should be suppressed.

997 is "documented" here: https://docs.microsoft.com/en-us/window ... --500-999-

Code: Select all

ERROR_IO_PENDING
997 (0x3E5)
Overlapped I/O operation is in progress.

You can safely ignore them.

Here's another example of a Microsoft error code that actually means there is no error:

Code: Select all

ERROR_SUCCESS
0 (0x0)
The operation completed successfully

The client already has filters for many error codes "that should not be logged", but this was a new problem associated with new hardware. So it is not on the current filter list.

Thanks for confirming. Hadn't appreciated the team was already aware of this "false error".

Still, at least those suffering from it might stumble across your post and breath a sigh of relief now.
