[Plugin WP Bestsellers] Server Load
-
Hi,
I am using WP 2.9.2. with some plugins, especially the commercial WP Bestsellers plugin, which creates a list of bestsellers directly from Amazon. The links to Amazon are php-cloaked (like http://my-domain.com/wpbuy.php?id=1).
My problem is a huge server load generated by WordPress itself and I am not sure, if it is a WordPress or a plugin problem. After creating / editing any post and saving, WordPress starts to access all links included in any post at least two times. In case of a larger bestseller list with 100 links there are at least 200 accesses from WordPress shown in my access logs like this:
ip.ip.ip.ip – – [29/Jul/2010:12:54:37 +0200] “HEAD /wpbuy.php?id=975 HTTP/1.0” 302 – “-” “WordPress/2.9.2; http://domain”
ip.ip.ip.ip – – [29/Jul/2010:12:54:38 +0200] “GET /wpbuy.php?id=975 HTTP/1.0” 302 13 “-” “WordPress/2.9.2; http://domain”
ip.ip.ip.ip – – [29/Jul/2010:12:54:38 +0200] “HEAD /wpbuy.php?id=975 HTTP/1.0” 302 – “-” “WordPress/2.9.2; http://domain”

ip.ip.ip.ip – – [29/Jul/2010:12:54:40 +0200] “HEAD /wpbuy.php?id=975 HTTP/1.0” 302 – “-” “WordPress/2.9.2; http://domain”
ip.ip.ip.ip – – [29/Jul/2010:12:54:40 +0200] “GET /wpbuy.php?id=975 HTTP/1.0” 302 13 “-” “WordPress/2.9.2; http://domain”When I create or edit several posts in a shorter time, I can find some thousands of accesses like this and the server cannot answer the requests, which leads to many error 500s in the logs and a non-accessible blog for half an hour.
Now the most interesting fact is, when I deactivate _all_ plugins the issue is still existing.
Maybe you got any idea? I am wondering if this is a general WordPress issue, a plugin issue, a server issue or whatever. Is there any way to break WordPress’ habit to access inpost links itself?
Thanks in advance!
Best regards
Dan
