Slow, not responding problems

[Paul Wood]

I started having problems with my blogs (I have 2 on the same server) this morning. They were both slow and unresponsive; I could not load the admin interface at all.

I entered at help desk ticket with my host, and this was the reply:

Hello Paul,

You will need to audit your code as when query these pages they are using an enormous amount of system resources and these requests are affecting other users on the box. Please optimize your code, if this site continues to use massive amounts of CPU we will be forced to disable the site until you can resolve this issue.

I told this that this was an extremely popular open source program, used on thousands of websites, and that it was working just fine yesterday. I also asked how they figured out that it was my site that was causing the problems. This is my 4th year running Pixelpost; did they just now figure out it was a problem?

Is there anything else I should ask or tell them? Anybody else experience something like this?

Please ask them to identify the source more closely. This way to general. As you mentioned it is running on several thousands of sites without any problem. We haven't identified problems with 1.71 (on 1.5 and prior there might be slow loading due to exif reading, but we fixed that).

Problem is you load both Minth and Google page add. These slow the site down.

Problem is you load both Minth and Google page add. These slow the site down.

Those shouldn't affect the admin pages, should it? Those have slowed way down, too, if they load at all.

I have a wordpress blog on the same server that is still running fine.

This is their latest post on the ticket:
When I login to the server and monitor the processes and hit your page it is using 99.9% of the servers cpu to process the request. Prior to responding I did try restarting apache and mysql to ensure that this was current and was not as a result of old sessions that had not been terminated correctly. Have you made any changes to the site at all that would affect they time it takes to process the request?

I told them I haven't made any changes for quite some time. And the strange thing is that BOTH my pixelpost sites (they are on the same server) are having the same problem.

Defensio is down. Their site is giving a 500 internal server error, which is then passed onto our blogs. Log into FTP and disable defensio by changing the name of the directory in the addon directory (or if you can do it in the admin panel). My site is working again. Now I just have to fend off the russian spammers myself :-

Renaming the directory didn't do it, but deleting it did. I've enabled Askimet.

Thanks!
