Subject: Large pages not parsed

Hi,

I've just installed dokuwiki on Kubuntu 7.10 and for the most part it's working fine, except that very large pages (in the realm of 20,000 words, but text only) aren't being parsed -- the wiki source just seems to be dumped unformatted (although the usual header and footer is still output). I can divide the page into two smaller pages which are both rendered properly, so as far as I can tell there isn't a problem with the wiki source, it's just a matter of the page size.

Is this a deliberate limit? Is there some configuration option somewhere that tells it the maximum page size to parse?

I'll attach a screenshot to show you what I mean.

Thanks for your help.

Dan

Increasing the max_memory_limit in your php.ini should help with this.

Please add [SOLVED] to the initial thread subject if you feel your question has been answered.

Thanks for your suggestion, Chi.

I've tried increasing memory_limit from 128M to 512M and I still get the same result. Could it really take more than half a gig to mark up 20,000 words of text? max_execution_time is 30 seconds and it never takes that long to run.

Any other thoughts?

I had the same problems with big tables.
Perhaps there is a troubleshoot because of too much plugins (love them....). Perhaps like chi write, by server parameters it is possible to improve this behavior ?

___> test on a fresh DokuWiki install without plugins, your page.
___> Explore your php.ini ... and find the good parameters. Perhaps you server is quite low hardware ?

Check your webserver error log, it should tell you what goes wrong. You might be hitting some PCRE limit somewhere.

Read this if you don't get any useful answers.

jm_zz: I am not using any plugins (I've only just installed dokuwiki). The "server" I'm using is just my laptop, 512mb ram, 1.7ghz Pentium. I really don't think it ought to be struggling with this. I have looked through my php.ini (which I haven't changed from the default kubuntu package apart from increasing the memory it's allowed to use) but nothing has leapt out at me. I tried to attach it, but I get "invalid attachment file" from the forum. I could copy-paste it if it's important.

andi: Nothing is appearing in my error log. Which I'd expect, because the entire page is being output, albeit not marked up -- and therefore it seems more likely that it is dokuwiki that is "giving up" somehow and dumping its source as an error mechanism, rather than this being a problem at the level of PHP or my web server. At least, that's my guess.
