wiki:req_5977

Version 2 (modified by bills, 16 years ago) ( diff )

--

This request came in on May 27. It has 2624 rows all of which are bycoord requests. These are the slowest to parse.

The request started parsing at 13:38 HST May 27. We can see this because that is the time stamp on the request file. At 15:55 it is about half done. 4994 jobs have been queued so far and all but 200 are requests for cleaned up data. So the parsing will probably complete around 18:00

The following is a diary of me watching this request process. If some faults occur this may provide a debugging and repair tutorial.
