169.229.194.42: Problem with Download New WUs

[DrBB1]

On 19 July, my F@H began to terminate intermittently after uploading a completed WU. At this point, my best guess right now is that the problem is related to server 169.229.194.42. [Before 19 July, I did not have any WUs associated with 169.229.194.42 for at least one week.] I have included excerpts from two logs for now, and can send additional ones, if needed, as they become available.

The issue seems[/] to be related to a problem downloading a new WU as the previous WU is finishing up. The first log excerpt (see about 23:03:44) shows that only about 33% of a WU downloaded from 169.229.194.42, and the log recorded "ERROR:WU00:FS01:Exception: Transfer failed" at 23:08:37. F@H attempted to repeat the download and stopped after 21%, but did not record another error message in the log. The log suggests that the WU that had just completed uploaded properly. I moused over the F@H task bar icon in the task bar and it indicated that folding was “Active,” but no menu opened when I right-clicked it.

I closed F@H and tried to restart it, unsuccessfully. To be safe, I rebooted, and it started fine. I included the entire log until the next stoppage below. Unlike in the previous log, this one shows that a WU was successfully downloaded from 169.229.194.42 at 2:51:31, immediately after I had rebooted, and it was apparently uploaded successfully on completion at about 11:52:59. A new WU, from server 171.67.108.60, also completed normally, but then F@H terminated again at 14:05:07 after a WU was downloaded from server 169.229.194.42. Unlike with the previous WU that failed to download fully from 169.229.194.42, there was no specific error message, although the log suggests only 54% of the WU downloaded.

14:05:09:WU01:FS01:Cleaning up 

My best guess at this point is that the problem has been with server 169.229.194.42, but I wouldn’t bet the farm on it. Although it is not mentioned in the second log excerpt, I noticed that the FAH Control GUI, showed Work Queue Status as “Download,” Progress as “0.00%,” PRCG as “0 (0,0,0),” and Work Server as “169.229.194.42.” Since I received one WU successfully from server 169.229.194.42 after rebooting with no folding in progress, it may be the issue is intermittent or that it arises only under specific conditions (e.g., when another WU is actively folding),” but I’m just speculating.

[Joe_H]

Do you have a particularly slow internet connection? I ask because your PC is taking 4-5 minutes to download about 500 KB of WU in a few spots shown in your logs. Or are you running large uploads/downloads that coincide with these problems on your network such as torrents that would slow the download. They might be timing out for that reason.

As for whether it is connected with just this one server, I see the slow downloads from at least one other server in your log.

[davidcoton]

It is known that the v7 client does not handle problems with uploads and downloads well. Slow transfers (from whatever cause) increase the likelihood of a problem, which the client cannot recover from. AFAIK the only current "cure" is a full client restart, often most easily achieved by a reboot.

This is a known problem that has been reported but not fixed (IIRC) as of 7.4.4.

...My best guess at this point is that the problem has been with server 169.229.194.42, but I wouldn’t bet the farm on it... but I’m just speculating.

That's possible, of course, but I'd expect other reports of people having troubles with that server and I'm not seeing them. I'd speculate it's something unreliable in your internet connection. The error does indicate that the transfer failed, and that can happen anywhere along the line.

When you rebooted, did you also restart your router/modem/etc.? Has your ISP been having problems? Do you run a BitTorrent concurrently?

[DrBB1]

I have had no particular issues with my internet connection recently. Generally don't have large uploads/downloads. Mostly keeping applications up to date (no torrents/megafiles). In fact, generally the only thing going on that I am aware of is folding. I have some maintenance programs work in the background once a week, but not during the times the problems showed up.

I will check back on download times of other WUs preceding the problem to see if they are much faster or consistent with these in line with Joe_H's observation. I'll also reboot my router just in case as bruce suggested, although I just clocked the download/upload speeds at 84/39 Mbps (faster than rated by my ISP) using Speedtest.net, and these are among my fastest speeds ever. If the problem is on my end, there may be something running in the background I 'm not aware of. As a backup plan, I may try to do a system restore, though I'd like to avoid that if at all possible.

Bottom line: it seems like this is a problem only I may be experiencing. In the larger scheme of things, that's a good thing. Still any other suggestions would be appreciated.
