Hello Planet,

Hi Maposmatic!

In case nobody has told you, although I suspect someone will have mentioned it...the last map to be successfully rendered was at 06:40 this morning. I can't find any maps after then that have actually rendered.


Yes, we've had a few hickups with our sql database: once one rendering job took too long (> 20mn) to perform its sql queries, then 1/ the rendering failed and got aborted, 2/ but not its sql backend which kept on running (and eating 100% CPU), so 3/ chances were very high that the next rendering jobs timed out, which caused the next to time out, etc. This is a perfect example of a domino effect.

As per this should be worked around since yesterday night. It doesn't prevent occasional jobs to time out (when the rendering area is large and/or dense or the DB very loaded), but it should prevent the jobs /after/ the timeout to be OK (=> no domino effect). We still need to optimize our requests to prevent the timeout from happening altogether.
