I'm using BOINC 7.6.9 on a Core 2 Quad 6600. I have the GPU disabled for BOINC. I'm running into a really weird upload problem. It seems that small files will upload OK and I can download files of any size from Rosetta. However, When I have to upload a large file, it uploads at high speed (about 45K Bytes per second) and reaches 100%. Then it waits for 20+ seconds at 100%, fails, and schedules a retry. I've seen this before. It can go on doing retries for days and then suddenly everything uploads and I stop having the problem for a few days. The server status shows everything is fine and other file transfers work. BTW, the current file having trouble is 1.65 MB. I am attached to several projects (WCG, POEM, Einstein, etc) and don't have the problem on any of those. David Have you read a good Science Fiction book lately? |

The last period of time on an upload is a confirmation that all of the data has been received by the server. So it almost sounds like the last buffer of data is getting stuck in a firewall somewhere in your network. Where it is making the connection ok, but the last buffer of data is (often) not being sent soon enough. Does anyone know of a network test (short of a full trace) that might help isolate the problem? Rosetta Moderator: Mod.Sense |

I finally got the uploads to work. I had upload speed limited to about 45K Bytes per second. I tried limiting the speed to 5KBps and that got an error as soon as 100% of the file was sent. Then, I tried completely removing the limit on upload speed and the files uploaded. I have no idea why this fixes the problem but I had 2 stuck uploads and they both uploaded as soon as I told them to retry. I'm on Windows 7 64 bit with BOINC 7.6.9 and DSL (5 Mb download / 512Kb upload). David Have you read a good Science Fiction book lately? |
