The LB machine is Redhat 9.0 with all but ports get headers php 22 and 80 firewalled. The servers on the web farm are Apache 1.3.x running, among other things, FastCGI and mod_perl.The problem: the web servers in the far are dropping errors into the logs, once or twice a minute (but probably will be more by morning load) to the tune of "request failed: error reading the headers".It seems to be a very select problem -- there are few relevant mentions of this one usenet or even the web, and many

are reports of worms or the posts were never followed up on. I was ready to give up and blame httpd 2.0 or mod_perl. But...I did some checking and creative grepping on my error and access logs on both the LB and the webheads and found something interesting. The errant requests were being passed from the httpd 2.0 front end, but the errors weren't directly caused by it.Instead I found that these are errors cause by someone issuing a "proxy request" to my site; but since the load balancer is not (anymore) configured as a proxy, it passes those "CONNECT // HTTP/1.1" requests to the webheads. The webheads in turn either don't do proxying or have it disabled and thus throw errors: "request failed: error reading the headers".This can be proved by running tail -f /var/log/httpd/error_log | grep headers in one window and tail -f /var/log/httpd/access_log | grep CONNECT in another -- whenever an "error reading the headers" message appears, a CONNECT message will also appear in the access log and they both will have the same timestamp.So in the end, in cases such as this, these errors are safe to be ignored. But for the sake of the Internet and you pocketbook, make sure your install of Apache isn't configured as an open proxy :) Post a new comment Error We will log you in after post We will log you in after pos

I don't see any relation to some specific browser or some specific request, it is totally random. Also it can not be the switch problem because I have the same problem on my other apache servers that are not sharing same switch. Till now I tried to: - update network card driver - raise RX from 256 to 4096 with: ethtool -G eth1 rx 4096 - bond second network card to the interface - google this problem many times but didn't find the solution or same issue.

2005-08-11 10:45 Hi, I managed to setup G2 and import my G1 albums. So far so good. But uploading new pictures does not work at all. Neither via GR nor via http://galleryproject.org/node/34386 the Web Interface. GR tells me to set LimitRequestBody and memory_limit which both is set. Uploading via Web gives me an instantaneous "Document contains no data" with the following error in default-error.log on the server: [Thu Aug 11 12:16:23 2005] [error] [client 213.157.2.234] request failed: error reading the headers, referer: http://www.nameofmygallery.de/gallery2/main.php?g2_view=core.ItemAdmin&g2_subView=core.ItemAdd&g2_itemId=15 This happens on any image no matter the size. I turned on gallery-debugging error reading and the moment I hit "Upload" for an image (Web-Upload) nothing is shown in that log. Only in the default-error.log. Therefore I am pretty sure this is some sort of Apache/PHP configuration error. But where to look? What next? I am officially out of ideas. Any help would be greatly appreciated!!!

Right after posting the question I found the answer. It was the DeepInspection of our local NetScreen firewall. It detected the upload like this: Name: HTTP: Apache mod_php php_mime_split() Heap Overflow Description: This signature detects heap overflow attempts against mod_php in Apache. Attackers may send a maliciously crafted HTTP POST request to execute arbitrary code on the server. Great. Just what I needed... Thanks anyways. wbrunner Joined:2007-02-27 Posts:1 Posted: Tue, 2007-02-27 07:57 Hi JP, One of my clients has the same problems. But the error is really old. Does that mean, that my client did not update the firewall for years or is it necassery to change the firewall-configuration?
