如何防止fwrite（）：由peer重置连接

Question

I have cron which is using fwrite function and after cron is running 1 hour it will crash with error:

fwrite(): send of 29 bytes failed with errno=104 Connection reset by peer

on line:

$fw = @fwrite($this->sock, $msg."
");

After this I always close connection by

fclose($this->sock);

It seems that it is something wrong inside PHP core and DNS resolver because after that I have some problems resolve hostnames to ip adrress. In my functionality is also used getmxrr() and gethostbyname() functions. How to prevent this problems?

Answer 1

After some experiments i used more working solution. I replaced fsockopen function with socket_create and socket_connect and its much much better. Function fsockopen sometimes not conneted correctly.
