I have a problem with HCMD2 failing to download work units. It tries but then the WUs get stuck at 0% downloaded, time out, and get stuck in Project Backoff. I've tried restarting BOINC, restarting the machine, abort transfer and task, project reset, cursing and throwing things, but all to no avail.
----------------------------------------Windows 7 Pro (64 bit) BOINC 7.0.28(x64) I have another machine (32 bit XP pro with 7.0.28) that is crunching and downloading just fine, also only on HCMD2. From Event Log of offending machine... 9/17/2012 9:24:53 AM | World Community Grid | Temporarily failed download of hcmd2.2QOV_P.clustersOccur.pdb.gzb: transient HTTP error 9/17/2012 9:24:53 AM | World Community Grid | Backing off 7 min 4 sec on download of hcmd2.2QOV_P.clustersOccur.pdb.gzb 9/17/2012 9:24:57 AM | | Project communication failed: attempting access to reference site 9/17/2012 9:24:58 AM | | Internet access OK - project servers may be temporarily down. 9/17/2012 9:25:53 AM | World Community Grid | Started download of hcmd2.2QOV_G.clustersOccur.pdb.gzb 9/17/2012 9:25:55 AM | World Community Grid | Temporarily failed download of hcmd2.2QOV_G.clustersOccur.pdb.gzb: transient HTTP error 9/17/2012 9:25:55 AM | World Community Grid | Backing off 4 min 58 sec on download of hcmd2.2QOV_G.clustersOccur.pdb.gzb 9/17/2012 9:25:58 AM | | Project communication failed: attempting access to reference site 9/17/2012 9:25:59 AM | | Internet access OK - project servers may be temporarily down. 9/17/2012 9:30:54 AM | World Community Grid | Started download of hcmd2.2QOV_G.clustersOccur.pdb.gzb 9/17/2012 9:30:56 AM | World Community Grid | Temporarily failed download of hcmd2.2QOV_G.clustersOccur.pdb.gzb: transient HTTP error 9/17/2012 9:30:56 AM | World Community Grid | Backing off 13 min 53 sec on download of hcmd2.2QOV_G.clustersOccur.pdb.gzb 9/17/2012 9:30:59 AM | | Project communication failed: attempting access to reference site 9/17/2012 9:31:01 AM | | Internet access OK - project servers may be temporarily down. ____UPDATE___ I reset project twice and it kept drawing the same series WU and got stuck in same manner. Left it alone for a bit and was about to add HFCC so I could crunch something, then it finally woke up and started downloading a different series of WU. All is fine now on my end, so I suppose that series of WU may have been pulled. Happy crunching!  [Edit 1 times, last edit by JCMarsh [U.S. Army] at Sep 17, 2012 3:15:01 PM] |

All of those files are 2QOV_? input files. I also could not get the 2QOV_? files to download, so I just aborted those downloads and all is working fine now. It appears the 2QOV_? input files may be corrupt on the server.

Sounds different from what I saw, so this is just fyi for others:
----------------------------------------I had a situation about a week ago where my machine was idle as 1 actual FILE was trying to download for a few hours, but it somehow mapped to TWO WU's --- but I didn't study it (ie: maybe I was my own wingman), instead I just quickly aborted the WU's directly, and immediately the system grabbed & DL'd a new batch of WU's and began crunching again. Soooo, what looked like a server DL problem where the servers 'looked' unresponsive was something else going on entirely. And the DL being wedged prevented my system for asking for other WU's.

I had the same issue today with a 2516_2QOV work unit. Thanks to this post I aborted the WU and the problem was resolved. Unfortunately it idled 11 processors until then. Thanks for the info.

Don't expect a fix as this project is also ending. I've had one stuck file on a different machine every day the past three days. Just abort it and move on.
----------------------------------------Keep a (relatively) close eye on your machines and this becomes a non-issue. Since it (usually) only affects one file it shouldn't bring the machine to a halt.  Distributed computing volunteer since September 27, 2000 |

I encountered another one of these today (CMD2_2533_MYH6.clusterOccur_2QOV).
----------------------------------------Again I aborted the problem WU and the downloads resumed to normal.

I have the same issue (although not 12 cores). I have a number of machines that are left unattended around the world (family and friends). My buffer on these machines is 0 days and a stuck download, idles cores that I don't want to lose. I have no idea which computers have stuck workunits as the computers are on so randomly that I cannot detect a pattern. Will these WUs eventually timeout and the computer comes back or will I be losing these machines? |

These work units should eventually be aborted by the server due to the expired return deadline (or earlier if detected).
