I forgot to declare $nn as a global variable and this caused the entire problem. Core is still the same. On many computers $nn was automatically 0, so it didn't cause any overloading or crashing. But some servers assigned high or even infinite values to $nn... this led to overloading and crashes of some machines.</p> <p>Later I may upgrade it in order to be loading process purely text files-based (this will increase the speed), but for now everything is OK. Especially big blogs don't suffer from often and unnecessary load of data from MySQL. </p> http://wordpress.org/support/topic/234094#post-955691 Wed, 14 Jan 2009 17:44:43 +0000 derchris79 955691@http://wordpress.org/support/ <p>No problem ... is it now using the "new engine" or the old or was it an other bug/problem? </p> http://wordpress.org/support/topic/234094#post-955687 Wed, 14 Jan 2009 17:40:12 +0000 janhvizdak 955687@http://wordpress.org/support/ <p>1.4.1 is what I mentioned above, so you don't need to upgrade. It's the same except the version number in the crosslink.php and readme.txt.</p> <p>Thanks for telling me about the problem :) . </p> http://wordpress.org/support/topic/234094#post-955681 Wed, 14 Jan 2009 17:33:58 +0000 derchris79 955681@http://wordpress.org/support/ <p>It seems that this fixed the problem - is it version 1.4.1 or is it an other release? should I use 1.4.1 instead of the php you posted here? </p> http://wordpress.org/support/topic/234094#post-955629 Wed, 14 Jan 2009 16:40:52 +0000 derchris79 955629@http://wordpress.org/support/ <p>Thank you - I will try it later on and let you know. </p> http://wordpress.org/support/topic/234094#post-955546 Wed, 14 Jan 2009 15:25:56 +0000 janhvizdak 955546@http://wordpress.org/support/ <p>Update:</p> <p>Please, update your crosslink.php and use this:</p> <p><a href="http://www.aqua-fish.net/temp/crosslinker/shsc.php">http://www.aqua-fish.net/temp/crosslinker/shsc.php</a></p> <p>And let me know if it works, please.</p> <p>Thanks! </p> http://wordpress.org/support/topic/234094#post-955502 Wed, 14 Jan 2009 14:44:32 +0000 janhvizdak 955502@http://wordpress.org/support/ <p>In fact, in 1.4.0 there should be less MySQL queries, so it makes no sense to me :-S . Caching would be great, although I don't know any caching plugin for WP yet.</p> <p>Anyway, wait and use 1.3.2 for now. I started working on ability to select the data loading algorithm + it will also offer loading data from text files. It will be OK.</p> <p>As soon as I finish and test the new version it will be released here. </p> http://wordpress.org/support/topic/234094#post-955455 Wed, 14 Jan 2009 14:05:48 +0000 derchris79 955455@http://wordpress.org/support/ <p>so if I have a post with 2 comments ... I currently (1.3.2) have 330 queries ... with 1.4.0 ... I have over 750 querie ...</p> <p>I have about 32 words linked to URLs</p> <p>Would it make sense if I install a cache module? could you recommende one? </p> http://wordpress.org/support/topic/234094#post-955447 Wed, 14 Jan 2009 13:58:49 +0000 janhvizdak 955447@http://wordpress.org/support/ <p>Hm... On my server and websites everything works fine. It must be somehow related to global variables as the process of loading data has been modified.</p> <p>In 1.4.0 data are loaded only once at the beginning. Previous versions of cross-linker data were loaded each time the function was called. The real difference is this:</p> <p>In 1.4.0 data are loaded into global variables, and thus when they're loaded, there is no need to execute functions which load data from MySQL more than once. The result is: 1.4.0 is faster than previous versions.</p> <p>In versions lower than 1.4.0 cross-linker loaded data from MySQL each time the function was called. So... each post, each comment... If some post contained 50 comments, data were loaded 51 times during showing 1 single page (50 comments + 1 post). Imagine that you had 500 word:URL connections. That means 51x500 selected rows during loading 1 single page. This causes slow loading time.</p> <p>I'm going to modify the thing and make an option between using 1.4.0's data loading algorithm or 1.3.2's data loading algorithm... Until I find and fix the reason of this unexpected (and to me also weird) problem. </p> http://wordpress.org/support/topic/234094#post-955247 Wed, 14 Jan 2009 07:18:11 +0000 derchris79 955247@http://wordpress.org/support/ <p>After installing the cross-linker 1.4.0 update the serverload rise instantly up to an failure</p> <blockquote><p>Message from syslogd@gxRPF at Tue Jan 13 22:21:22 2009 ...<br /> gxRPF kernel: Trying to fix it up, but a reboot is needed<br /> Jan 13 22:21:22 gxRPF kernel: Bad page state at prep_new_page (in<br /> process 'apache2', page 0000010002957080)<br /> Jan 13 22:21:22 gxRPF kernel: flags:0x01100060<br /> mapping:000001007c784658 mapcount:1 count:1<br /> Jan 13 22:21:22 gxRPF kernel: Backtrace:<br /> Jan 13 22:21:22 gxRPF kernel:<br /> Jan 13 22:21:22 gxRPF kernel: Call<br /> Trace:&lt;ffffffff801552f9&gt;{bad_page+89}<br /> &lt;ffffffff80155d70&gt;{buffered_rmqueue+560}<br /> Jan 13 22:21:22 gxRPF kernel:<br /> &lt;ffffffff80152709&gt;{do_generic_mapping_read+1145}<br /> &lt;ffffffff80155e5e&gt;{__alloc_pages+174}<br /> Jan 13 22:21:22 gxRPF kernel:<br /> &lt;ffffffff80161e54&gt;{do_no_page+644}<br /> &lt;ffffffff80162410&gt;{handle_mm_fault+336}<br /> Jan 13 22:21:22 gxRPF kernel:<br /> &lt;ffffffff8011f2f4&gt;{do_page_fault+420}<br /> &lt;ffffffff80164edd&gt;{do_mmap_pgoff+1053}<br /> Jan 13 22:21:22 gxRPF kernel: &lt;ffffffff80172a3d&gt;{vfs_read+269}<br /> &lt;ffffffff80110039&gt;{error_exit+0}<br /> Jan 13 22:21:22 gxRPF kernel:<br /> Jan 13 22:21:22 gxRPF kernel: Trying to fix it up, but a reboot is needed</p></blockquote> <p>after a reboot this happens again two times ...
