I had a result uploaded just before the outage.
The server was out when reporting the completed task but 4 hours later it succeeded in reporting the task. However, it still shows up as "In Progress" in my Results Status report. Could someone please sort this out? I attach a copy of my events log for the relevant period.

Mike,
I have added a post to the end of this thread: https://secure.worldcommunitygrid.org/forums/...32678_lastpage,yes#367931 that discusses the issue. |

Thanks, knreed.
I had assumed that it was a Schistosoma problem rather than the wider WCG. I just needed that result for my Bronze! Mike |

One further thought.
As the task had successfully uploaded, is that not sufficient to avoid re-sending the task? If it is then it would be a waste of crunching time to do it again. Mike |

Hi Mike.Gibson,
The explanation knreed posted says that the result was lost on the server. So we will have to recrunch it. Lawrence |

Hi, Lawrence.
Yes, I read that, but I was unsure what it actually meant. There are 2 stages so far as I can see at the end of the task. The first is the Uploading and the second is the Reporting. Does it mean that the Uploading has been lost or the Reporting or have both gone? I have never seen an explanation as to what happens when. I was just wondering if the Uploading contained the information needed and was still there. If so, it should be retrievable. Likewise anyone else's "orphan" Uploads from that period. Mike |

Hi Mike.Gibson,
I am a bit uncertain. A while back, knreed said that he had found 2 missing results when he first started investigating this. Most recently, he said that he would resend the work units with missing results. To me, that sounds as though there is no standardized automated way to retrieve them from where they were misfiled, but I don't know. But I suspect that knreed is taking the safest course of action by resending them. There are enough other problems that have to be fixed quickly. Lawrence |

They have to be resent. It is possible that we could have written a script to navigate through all of the uploaded files on the server and matched uploaded files with results that were still in the database as 'in progress'. However, there would be no way to differentiate between results that were marked in progress due to this issue vs results that had simply been uploaded and simply not yet reported. Additionally, by the time the script as ready, tested and running, many results would have already been re-issued. As a result the choice was between possibly creating a bigger issue vs letting the system run its course and fix itself. Given that we had fixed the original issue and there were other issues outstanding, we choose the 2nd option.
We are not happy that this issue happened. We take great pride in running this system efficiently and correctly. Most of the time we are successful with this. Unfortunately, this time we did not meet yours or our own expectations. For that we are very sorry. |
