Hello,

Sending a newsletter to more than 3000 subscribers ends unexpectidly after some 2800 are sent (last time 2891).

It's not a PHP timeout. First, the time set in PHP config is far enough to complete sending the newsletter to all the subscribers. Second, the is no "Maximum execution time exeeded" warning in the Apache error logs as those I can see when such an event occurs, on this system. (The script crashes after 457 seconds out of 800).

It doesn't seen to be a size issues either. There is no "Allowed memory size exhausted" warning in the Apache error logs as those I can see when such a event occurs on this system.

On this system, PHP is running as fastcgi. When the script crashes, Apache logs a warning and and error :

[warn] ... (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[error] ... Premature end of script headers: index.php

I didn't read about a subscribers number limit in the documentation. Is there such a limit ?
