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, $msg."\r\n");
After this I always close connection by
fclose($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?
I got answer from PHP community like this:
Inside fwrite is part code of streaming and sometimes it could happen. They said that it is impossible to fix it on fwrite because it can change some functionality of other functions which using streaming too.
Soo in finaly its property not fault.
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.

I've got a fairly simple cron job that pulls down some files from an FTP server - none of the files are particularly large, but I'm constantly getting the following:
Connected to voip.colefabrics.com, for user colefabrics\absolute
Warning: ftp_get(): Opening BINARY mode data connection. in /home/www/colefabrics.com/httpdocs/libs/classes/class.ftpObj.php on line 56
There was a problem while downloading website/items.csv
Attempt 2:
Connected to voip.colefabrics.com, for user colefabrics\absolute
Warning: ftp_get(): Opening BINARY mode data connection. in /home/www/colefabrics.com/httpdocs/libs/classes/class.ftpObj.php on line 56
There was a problem while downloading website/items.csv
...snip...
I've been through all the other posts relating to this, tried to enforce passive mode, increased the timeout, but nothing is working.
Does anyone know what might be causing this, and what I can do to try and resolve it?
To confirm, it's working fine via a 'normal' FTP client, it's only via PHP that I have a problem.
I have been working on my first PHP contact form.
I have also been running into some problems. I have gotten the files to all talk to each other, and it has gotten to the point where it looks like it is going to work. But, after you input the information in the form, press send, it comes back with this error:
Deprecated: Function eregi() is deprecated in /home/content/12/11666412/html/phpMailer/class.phpmailer.php on line 594
Warning: fsockopen() [function.fsockopen]: unable to connect to smtp.gmail.com:587 (Connection refused) in /home/content/12/11666412/html/phpMailer/class.smtp.php on line 122
Thank you!
So, I assume 2 things:
1: I should try using a different port # for connecting to google (587 has worked for me in the past on a different server, is this something that sometimes changes?). What port number should I be using?
2: Something is wrong in the PHP mailer files (that I downloaded from the PHPmailer site). Should I try redownloading them? I doubt anything is wrong with the PHPmailer, seems to be a very reputable tool that people use, the code is too advanced for me to analyze.
Any help would be appreciated.
My error output looks like this:
PHP Warning: fwrite(): SSL: Broken pipe in /home/whitelot/public_html/webservies/mylastwishnew/apnstest.php on line 89
and then every subsequent write to that resource gets the error:
PHP Warning: fwrite(): SSL: Broken pipe in /home/whitelot/public_html/webservies/mylastwishnew/apnstest.php on line 89
It works for a while, for maybe a few hundred messages/payloads, then all of a sudden pipe breaks and water goes all over the floor.
Anyone have any ideas if there is a good fix for this problem?
I found that using the
'keep_alive' => false
option for
new SoapClient($url, $options);
solved the issue in my case. It seems like if you don't use keep_alive = false, the SOAP connection tries to re-use a previous connection, which gets rejected by SSL. See https://bugs.php.net/bug.php?id=60329
Also, make sure this is not a question of max_execution_time or another limit that might prevent the SSL connection to finish successfully.
I'm getting what looks like rather serious database errors in my CodeIgniter application. In the log file it says:
User anders already has more than 'max_user_connections' active connections
And there are several hundred of those lines... I've read a bit by Googling, and some suggested that it was because you didn't close the connection after it was used, but others said that this was nonsense, and that the connection was automatically closed (which is what I read in the docs too).
Also, later in the log file, I have these error messages:
ERROR - 2011-10-12 10:50:19 --> Severity: Warning --> file_get_contents(http://localhost/expertinfo/error/error_general) [function.file-get-contents]: failed to open stream: HTTP request failed! /Applications/MAMP/htdocs/expertinfo/application/errors/error_general.php 4
This seems to have something to do with the fact that I'm using a custom error page by using
echo file_get_contents($config['base_url'] . 'error/error_db');
to redirect to a custom page.
Finally, I'm also getting:
ERROR - 2011-10-12 10:52:19 --> Severity: Warning --> mysql_pconnect() [function.mysql-pconnect]: Can't connect to MySQL server on 'mydb24.surftown.se' (4) /Applications/MAMP/htdocs/expertinfo/system/database/drivers/mysql/mysql_driver.php 88
In these last two, I don't understand what the local path is doing there (The path to my CodeIgniter app on my computer). I mean this is a part of the system folder and the one on the remote server should be used, right? I have the database set up as the remote database, and I don't have any local paths as far as I know....
So why does this happen, and what can I do about it?
Please help, this seems rather urgent. I'm a bit of a newbie to both php and CodeIgniter too, so a clear and simple answer would be greatly appreciated!
Local path as I see shows you file where your error happened, because your driver /Applications/MAMP/htdocs/expertinfo/system/database/drivers/mysql/mysql_driver.php possible on it's 88 line contain connect() function and it raise an exception
The problem is with your mydb24.surftown.se remote server, you should check your access credentials, etc. to find what exactly happened
Just an FYI, mysql_pconnect is usually a bad practice on shared hosting (you can see why here:http://stackoverflow.com/questions/1830830/advantages-disadvantages-of-pconnect-option-in-codeigniter)
You might just disable pconnect on application/config/database.php and see the error going away as your connections will be realluy lower.
For the quote: "mysql_pconnect is usually a bad practice on shared hosting".
I changed to use mysql_connect. It made no difference.
I am working on a script that fetches csv files from a web server. I am using file_get_contents presently. Sometimes i get the message
Warning: file_get_contents failed to open stream: Connection timed out
I assume it can be due to website being down. Or can there be a situation where the website is fine but still this warning shows up. Also what advantage does CURL provide over this function.
this is because the remote url is having 404 error.
For accessing remote files, you should use cURL. You can set cURL to timeout quietly if the remote server takes too long.
