Hello,

 

I am experiencing a new issue since recent update from WP 3.3 to 3.3.1 and SP 5 update to latest 7759 build.

The problem I found is connections to the web server to itself from the eth0 interface on the machine. In apache error log, the connections are related to files refered on the Forum where the url is truncated on display.

 

One exemple of these url is, from here:

http://www.arctablet.com/blog/.....te/page-9/

The link to http://www.arctablet.com/blog/.....ols057.apk

shows as http://www.arctablet.com/blog/…..ols057.apk in the forum.

I have no problem with the truncated display as the link points to the correct place. My problem is that this links is somehow checked and accessed by SP or WP and gives hundred of errors in apache log:

46.105.107.12 - - [22/Jan/2012:17:43:28 +0100] "GET /blog/.....ols057.apk HTTP/1.0" 404 687 "-" "WordPress/3.3.1; http://www.arctablet.com/blog"

 

This is rather embarassing because these queries comes in hundreds a minute and I can't seem to find their origin.

 

I am requesting here as the files not found errors all relate to links from the SP forum, but I do understand that it may not be linked, and may just be a WP or WP plugin issue. I am just relating the problem to the recent SP & WP updgrade.

Are there any background checks on forum posts contents recently introduced in SP ? Do you have any idea or lead to check on the server setup ?

Thank you.

 

Edit: I made some extra tests, disabling all WP plugins one by one. The issue went away after the SP plugin was disabled and came back when I readded it, so it's quite obvious the problem has some relation to Simple Press.

Also I just tried latest SP 7781 build, the problem is still there.

For the moment I had to deny these connections thru iptables on the machine, else the server gets satured after few minutes frown

I am probably a little out of my depth here as these are areas out of my area of expertise but are you just referring to the url shortening giving you problems? If so - and obviously it would be better to get to the bottom of it - but have you tried turning it off in the forum options?

Well, yes the problem is linked to the shortened url, at least partly.

It's good to know that's changeable, I'll have a look and let you know.

Thank you.

I changed the url shortener lenght to 0 (unlimited characters) and unfortunately the problem is still there.

I have to leave the iptables firewall on else my server ressources get quickly exhausted.

I hope that a better solution could be found, Mr Papa any ideas ?

Where do we turn off the URL shortener?  Is it in the control panel or do we have to code it somewhere by hand?

I am afraid I am totally clueless here...  to me the url looks completely borked on the server, but you say it works????

and we certainly dont see such errors nor has anyone reported such a thing...

is this only occurring for you on blog linked topic urls?

Well the forum does work, there is just this "ghost" connections issue that is a bit of a problem, as it is saturating the machine.

I hope I am not the only one with this issue and we can make progress in understanding and solving it.

I have not yet understood which page or links are affected, but it does not seem to be related to blog linked topics...

oh, we are not giving up...  but yes, thus far, you are the only one with such an issue...

might you have any customizations (ie non wp standard) in your .htaccess?

Nope, it's almost stock, I just somes rules to have expire headers on images, watermark some images and a few rewrite rules for Wordpress. 

Ok, let's keep the issue open, I can live with the firewall filtering on my server... I'll have a look over updates if situation improves.

 

Actually I am more concerned about the forum speed issue (see here https://simple-press.com/suppo.....ox/#p97254)
