Description Chris Sherlock 2011-01-24 21:32:15 UTC
When I visit the following URL http://en.wikibooks.org/w/index.php?title=Special:Collection/render_collection/&colltitle=Wikibooks:Collections/Linear_Algebra , I eventually get the following error:


An error occured on the render server: RuntimeError: command failed with returncode 9: ['mw-render', '-w', 'rl', '-c', 'cache/e7/e76998e81bd718d8/collection.zip', '-o', 'cache/e7/e76998e81bd718d8/output.rl', '--status', 'qserve://localhost:14311/e76998e81bd718d8:render-rl', '--template-blacklist', 'MediaWiki:PDF Template Blacklist', '--template-exclusion-category', 'Exclude in print', '--print-template-prefix', 'Print', '--print-template-pattern', '$1/Print', '--language', 'en']

Comment 1 Volker Haas 2011-01-25 12:56:45 UTC
Rendering of the above article collection fails since it takes too long. Currently there is a timeout of around 30 minutes after which render jobs are killed. Try splitting the collection into smaller chunks.

Unfortunately the timeout can't be increased since this increases the load on the servers too much.

Comment 2 Chris Sherlock 2011-01-25 13:44:55 UTC
This didn't go for 30 minutes, it lasted about 30 seconds...
Comment 3 Bawolff (Brian Wolff) 2011-01-26 14:59:01 UTC
Also, if that is the case - the servers should give a more descriptive error message.

Agreed. I've seen people complain about this *exact* same error before, and the stack trace is less than useful.

FWIW, I don't think WONTFIX is the correct answer here, but I don't know Collection so it's not my call.
Comment 5 Chris Sherlock 2011-01-26 21:16:38 UTC
Just a note about the error - the formatting looks fine in this bug, but because it is just spat out without any HTML formatting it all runs on to one line. At *least* put some <br/> tags after the end of the line, please!
Comment 6 Volker Haas 2011-01-31 10:56:54 UTC
The collection can now be rendered to PDF. Rendering of math formulas now uses caching which speeds up rendering of the orignal collection almost tenfold. 

I agree that the error message is not helpful. Fixing this is currently not planed though.

Thanks Volker, much appreciated :-)
