unable tp get wu from 171.64.65.124 and 171.64.65.100

[hisui]

I can connect that server in browser (401 HTTP UNAUTHORIZED /) both ping and trace seems fine.This problem has lasted over 24 hours
also http://assign3.stanford.edu:8080/ doesn't load complete(always stuck at 80-90%)
other server such as 155.247.166.219:8080 works fine.(seems they are hosted in other network)
ping result

I was able to connect to all servers you mentioned without any problem, so that points to a network issue between your system and the servers and not the servers themselves. Is there something running on your network or the ISP you are connected to using a lot of network bandwidth for streaming video or torrent? Or are you connected by a wireless connection that is being interfered with by distance or other devices? I mention this because the upload and download speeds shown are relatively slow, and I am comparing them to my DSL line.

There also is a known issue with the network code in the folding client, it can sometimes fail to retry a download or upload that fails for some reason. If this happens the client will just sit there and never retry the connection. It is more commonly seen when there are network problems, and there are some slight improvements in the current version 7.4.4 client. When this happens the only way to get the download or upload to resume is restarting the FAHClient process whether by rebooting the system or manually stopping and restarting that process.

[hisui]

thx for ur reply,currently the problem has automatically resolved by itself,seems it's isp based problem,I didn't do a thing

[TwistedKestrel]

I think there's something up with at least 171.64.65.124, I'm running into the same thing now. Noticed the CPU slot on my client stalled, stopped FAH (had to kill the process) and started it again, and then I got this.

Ping and tracert don't show anything unusual.

[bruce]

How long did you let it retry before you decided to kill the process? Sometimes it takes 5 or 10 minutes before the client will abandon a download connection and connect to another server. The log you posted only shows two download attempts about two minutes apart.

The server logs indicate the server has been normally active over the past 8+ hours.

[Joe_H]

Also take into consideration that this is a busy server, I have seen as many as a couple thousand WU's listed as returned over the course of an hour.

[Grendel]

[..]Noticed the CPU slot on my client stalled, stopped FAH (had to kill the process) and started it again[..]

Had/have the same thing going on three different machines -- CPU and GPU clients all stall out (indefinitely) while receiving a new WU. First noticed it on Sat, ever since I had to Pause, Quit, Kill, and restart the clients to get a new WU.

Edit: Notice the time stamps at the end:

How long did you let it retry before you decided to kill the process? Sometimes it takes 5 or 10 minutes before the client will abandon a download connection and connect to another server. The log you posted only shows two download attempts about two minutes apart.

The server logs indicate the server has been normally active over the past 8+ hours.

Well, about ten minutes after that, I restarted the machine entirely and started the client again and left it overnight. Timestamps are in the same day as the previous log.

there is something wrong with this server. had to dump 3 units when i got home from work. they were all 9015. they were worth near zero so they had been hung for awhile. there is no telling how long they were sitting there and i am not digging through the logs to find out. just have someone take a look at the server. it is futile to continue folding units from this server as it is not uploading them.

It is not a general problem with this server, almost all of my WU's for the last couple weeks on three different systems have come from that server and have been returned to that server. Quite a few others are also using this server with little to no problems, as I mentioned earlier in this thread over 2,000 completed WU's an hour are being uploaded most of the time.

There are a very small number of reports of issues, and almost all appear to point to networking issues between the persons reporting them and the WS. That may be on the persons own network, or issues with their local ISP, it is not clear which.

There are a very small number of reports of issues, and almost all appear to point to networking issues between the persons reporting them and the WS. That may be on the persons own network, or issues with their local ISP, it is not clear which.

I don't think that's a valid argument- if it were "local" problems it's unlikely that only two Stanford servers would be involved.

I had a stuck P9014 this morning- coincidence only goes so far.

It's not impossible that there's an intermittent problem, which I'll concede will make it a pig to trace

Or your stuck WU coincided with a period of time that this server was actually in the Reject state. There were several periods of this last night, the last was for about an hour and ended by 23:20 PDT. With the time difference, that is morning for you. Since then whatever was causing the server to go into Reject status appears to have been corrected.

Unlike yours, many of these other reports did not happen at a time that the server was verifiably offline. Yes, it might be an intermittent problem on the WS end, but I would expect more frequent reports given the high volume of work downloading and uploading. And no, these are not the only two Stanford servers with occasional reports of download or upload problems.

... there is no telling how long they were sitting there and i am not digging through the logs to find out.

There is no need to dig through the logs, FAHControl will show the time a WU was assigned and the two timeout values. WU's will get bonus points up until the first, and base points after that until the expiration time.

Had/have the same thing going on three different machines -- CPU and GPU clients all stall out (indefinitely) while receiving a new WU. First noticed it on Sat, ever since I had to Pause, Quit, Kill, and restart the clients to get a new WU.

Is your internet connection by satellite or is there some other reason why it seems to be operating in half-duplex? Most people's connection can handle both an upload and a download concurrently and that is usually more efficient. Since that isn't working for you, we can probably avoid that condition by adjusting next-unit-percentage.

In your case, next-unit-percentage is set to 99% so the download begins at 11:54:18 but is unable to finish by the time the upload begins at 11:57:33 causing your connection to fail. (I have no explanation for why your connection can't do that.)

You can choose one of two options. Set next-unit-percentage to 98% or even 97%, allowing enough time for the download to complete before the upload begins.

The other option would be to set next-unit-percentage to 100% which may or may not turn out to be a better option for you.

Thanks for taking the time to respond. I don't think my connection has anything to do w/ it (altho there's no way to know for sure.) I'm folding at two sites (same ISP but different paths), happened at both of them. I have had this ISP for almost a year w/o ever seeing this problem before (been folding for ten years now.) Right now it seems to be working. What I find interesting is that the client apparently doesn't let go of the TCP connection even after two days (!), that may be worthwhile looking into.

Edit: I see what you mean -- WU is d/ling VERY slow (that's a 20Mb connection..), not finished when the upload starts. Normally I wouldn't expect that to be a problem tho, port 8080 should only be used for the initial connection negotiation if I remember my TCP/IP stuff right.. Still think the client should terminate the d/l after a reasonable period of inactivity ?

Edit2: having to kill FAHClient.exe once this happens could point to the hang happening w/in the windows kernel, wonder if a recent update messed things up...
