The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

php/cron/wget returning "End of file while parsing headers" or "Empty Reply"

Asked by syrma in PHP Scripting Language, Linux, Apache Web Server

Tags: , , , ,

Hello.

I have the following problem:
I have a php script, which is run every day by cron.
The cron runs wget http://mydomain.com/cronscript.php

Unfortunately, for some reason the script cannot get executed to the end all at once. The cron is restarted multiple times, first time on 15 minutes, after that like every 1-2 min. I'm receiving the following message:

......
--02:19:01--  http://mydomain.com/cronscript.php
  (try: 7) => 'cronscript.php'
Connecting to mydomain.com[ip]:80... connected.
HTTP request sent, awaiting response...
End of file while parsing headers.
Retrying...
--02:21:47--  http://mydomain.com/cronscript.php
  (try: 8) => 'cronscript.php'
Connecting to mydomain.com[ip]:80... connected.
HTTP request sent, awaiting response...
End of file while parsing headers.
Retrying...

It usually takes around 7-8 tries to get to the end of the script.
The script itself might get pretty heavy and takes long to execute, as it uses qmail-inject to send newsletters to multiple subscribers. However it starts with
set_time_limit(0); //set max execution time 0 - forever

... So, this shouldn't be a problem at all. Additionally, I have the same stuff running on another server, with twice as many subscribers, and works perfectly on the other server. I tried to change wget with curl, the same thing happens: works fine on the "bigger" server, returns an error message in the "smaller" server:
curl: (52) Empty reply from server.
The script runs fine on both servers if there are no any newsletters to be send for the day.

I guess my question is, if anybody has an idea what is causing the script not to get executed all at once, what does this message "End of file while parsing headers" means and how it can be corrected to run as it's on the other server. What might be setting this limit - 15 minutes, as it's ignoring my php setting for any reason?

Thank you
