My experience is the same as Andy’s though the english/fun topic when it loads, loads all the way… all or nothing… and the non forum pages that dont load for me is random and much less frequent than say the engligh/fun topic…
I’m talking with the hosting people to see if they can help me. So far they aren’t greatly helpful. The latest response was “I am more than happy to help. I’d be more than glad to have whatever changes you need made done, however at this time, I’m not aware of anything that would need to get made for this script to function properly. IF you could ask simplepress what changes could be made to allow for this script to function properly.”
So, do you guys have any ideas of what should be changed? Of course most of the things recommended so far I’ve made myself but, anyhoo.
Personally I am not a server expert. Actually I am hardly a server novice. You need Steve for that!
But I would like to investigate what it is that is hanging the site so often and randomly – and this is NOT just in forum pages…
I have no recommendations either… but it is site wide, not just forum, though as I have said, the forum ones that have an issue seem to be much more frequently than non forum pages…
you php memory seems sufficient… what is the php max cpu time setting?
and oddly not sure why the three of us are getting differently results… I never see a partial page load – you and Andy do… and when I get no page load, I see absolutely zero http activity or requests – nothing loads (no css, no js, nothing)…
knew the memory was fine… others are too… stumped, but continuing to think on it…
for grins and a quick test, can you switch to the default wp theme? just want to rule things out…
I just tried Twenty Thirteen, but the results were the same. I reverted the change back to our theme so the owner of the site doesn’t lose his mind.
okay, thanks for the try… didnt think it would matter, but at this point, ruling out things…
still pondering…
Ok, I have a new piece of data.
I am running on a Mac. So I created a Ubuntu 12.04 Server VM in Parallels, installed a LAMP stack, installed WordPress, and then copied the entire kyusho.com WordPress + Plugins installation over, along with the database.
Guess what, the forum posts work every damn time. It has to be some kind of server configuration with InMotionHosting.
that’s what I have been getting at since its unique… doesnt mean sp is not involved, just that its something not encountered before…
first, I would kill mod_security and leave it off… its no good anyway…
we do have other users on InMotionHosting so I dont think its something general with them… I still hope to get back tonight and play with some more settings…
what is really puzzling to me here, is when a page wont load – whether non forum or forum (and again, the english/fun is way more often than non forum page), I get no http activity… nothing, zero, zilch… I dont get that…
It means nothing is happening… first http request should be the page, but that doesnt even occur… then you should get http requests for each css file, js file, every other external reference, images, etc… but I see zero activity… when it does load, the http activity is normal…
I got some support from my webhost, and they said the following:
We found that your WordPress forum was making external requests, which queue DNS lookups using TCP port 53. Most DNS resolvers use only UDP port 53. Since your configured DNS resolvers on vps5936 have TCP port 53 blocked, the DNS lookups hang until they timeout. You can place “define(‘WP_HTTP_BLOCK_EXTERNAL’, true);” (in “wp-config.php”) to block external requests, which is not a good fix. You should ensure that WordPress is using UDP port 53 to make DNS lookups.
Does this make any sense to you? My forums now load, but it looks like they could stop working if the server reboots. Is this something the forums do?
Thanks!
No, the forum does not make requests over a specific TCP or UDPport.. we are just a plugin for SP and just use whatever wp is set up for… This is confirmed by other wp pages having the same issue (albeit less frequently)… and also that the forum ones work sometimes…
Why would it stop if the server reboots? whatever change they made should be more permanent, no?
They said they made a change to some DNS routers, but they would get reset if the VPS restarted… *shrug* I don’t know of why a plugin would force a DNS request over UDP, that seems like something that would be in Apache or PHP itself, not the application.
I didnt even know that wp could try to use different ports or protocols… I mean certainly there is things that can be done in the http class of wp, but you would explicity have to configure that somewhere in the wp config, I would think…
