Alright, I can reproduce:

Request: POST http://uk.wikipedia.org/w/index.php?title=%D0%92%D1%96%D0%BA%D1%96%D0%BF%D0%B5%D0%B4%D1%96%D1%8F:%D0%A1%D1%82%D0%B0%D1%82%D1%82%D1%96,_%D1%8F%D0%BA%D1%96_%D0%BF%D0%BE%D0%B2%D0%B8%D0%BD%D0%BD%D1%96_%D0%B1%D1%83%D1%82%D0%B8_%D0%B2_%D1%83%D1%81%D1%96%D1%85_%D0%B2%D1%96%D0%BA%D1%96%D0%BF%D0%B5%D0%B4%D1%96%D1%8F%D1%85/stat&action=submit, from 208.80.152.18 via sq72.wikimedia.org (squid/2.7.STABLE9) to 208.80.152.70 (208.80.152.70)
Error: ERR_READ_TIMEOUT, errno [No Error] at Tue, 15 Oct 2013 15:30:45 GMT 

I wonder how many templates are used on that page, and if they use Lua.
Comment 3 herzi.pinki 2013-11-21 07:37:10 UTC
I had a look at the parser measurement included in each rendered page's source code:

NewPP limit report
Parsed by mw1086
CPU time usage: 7.892 seconds
Real time usage: 8.483 seconds
Preprocessor visited node count: 399/1000000
Preprocessor generated node count: 3180/1500000
Post‐expand include size: 19211/2048000 bytes
Template argument size: 0/2048000 bytes
Highest expansion depth: 2/40
Expensive parser function count: 0/500

Does not look critical in any way.

My observation on large pages is that the edit & save is done correctly, but the rendering of the altered page back to the browser fails due to time limits. So refreshing the page after a while will show the changed content.
