I received this message after long time of using the same application without programming changes:
Warning: Unknown(): write failed: No space left on device (28) in Unknown on line 0
Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
I thought is servers problem, but these messages are not showing in every computer. Is this some sort of problem with settings? What can I do to fix this?
From Bytes.com
The filesystem containing /tmp is
full. Your system administrator should
fix this immediately - and if they
haven't noticed you ought to question
what level of support you're getting,
since a lot of things will go horribly
wrong if /tmp is full.

I am currently working on a user registration system for a client on GoDaddy hosting.
I have previously never had this sort of issue before on Hostgator and while testing locally on a PHP test server on OS X.
It's a fairly simple script too. common.php accesses the MySQL database, all of the pages (login, register, etc.) include common.php. Sessions start when the user logs in, etc.
I see the following errors at the top of the page:
Warning: session_start(): open(/home/content/10/12114910/tmp/sess_trmok9fgtb527mjp21a76shf54, O_RDWR) failed: No such file or directory (2) in /home/content/10/12114910/html/common.php on line 86

The following errors are at the bottom of the page.

Once again, this is only a GoDaddy issue. My client was originally on Windows hosting and this just did not even work at all and I switched them to Linux hosting.
They were on PHP version 5.3 and I changed it to 5.4 and I have still had no luck.
I have never messed with a php.ini file. Would I need to create one? I have heard that uploading it into the public_html folder overrides the one on the server even though we are on a shared hosting plan.
Would I also need SSH access to create a tmp folder and set proper permissions for it?
This is usually quite easy to fix on crappy providers (I don't recommend GoDaddy, by the way).
Here is how I'd go about fixing it, hopefully it will help you.
Step 1: Make a directory and call it _sessions or something of that
nature.
Step 2: Give it a chmod of 775 so that the web server can write to it.
Step 3: On the first script that runs, right at the top place session_save_path("./_sessions");
Step 4 (optional, but recommended): Add either deny from all in a .htaccess file to prevent people from getting to the directory, or simply chmod 776.

What error is this?
Your disk or partition is full
Take a look at docs.
Make sure the (default) save_path is writable by the user your web server running as.
And check if there's enough space on your disk to write session data.
I have just moved over to a linux server on my shared hosting to see if it is less rubbish than a windows server on godaddy (I have been stupid enough to have paid them 12 months up front so I am stuck with those idiots now). I am now no longer able to use any kind of sessions at all.
They have got back to me saying that it is up to me to resolve the issue to get it to work... yes that is right... TO GET SESSIONS TO WORK! Excuse me if I seem a little irate but I am furious.
Can someone please inform me how I can in some way get sessions to work on an Apache server? I have never had to set this up before because it has never been a problem. As soon as I do:
<?php session_start() ?>
... it is just coming up with about 8 lines of errors saying that:
Warning: session_start() [function.session-start]: open(/var/chroot/home/content/30/10247530/tmp/sess_sgruthqkbhfms6ekcle2l0n6i5, O_RDWR) failed: No such file or directory (2) in /home/content/30/10247530/html/sessionthing.php on line 2

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct () in Unknown on line 0
I have tried creating a php.ini file and I still cannot get it to work properly. I have checked the settings using phpinfo() and I genuinely do not know where to go from here.
EDIT: There are a few things appearing down the side of the page now pointing to similar problems. For some reason I did not come up with those when I did a search. One of them is even closed: https://stackoverflow.com/questions/11374110/session-start-errors-on-godaddy-server?rq=1
That one says that they got it resolved with Godaddy so I think I will have to go back to them and tell them to sort it out. It is not that I do not want to learn how to configure the server... it is just that sessions should just work.
Make sure that there are no other <?php session_start() ?> declared, and try set your own session temp path,
<?php
if (!is_dir(session_save_path())) {
session_save_path ('your/custom/existing/directory');
}
session_start();
?>
PHP is trying to save the session in /var/chroot/home/content/30/10247530/tmp/, and it can't open that directory (either because it doesn't exist or because it doesn't have write permissions to it). Investigate PHP's access to this path and I believe that you'll get your sessions working - maybe you overlooked a config variable when you migrated your code to the new server?

Getting these errors after uploading a certain amount of content. Also, noticed that can no longer log in to admin panel. Could this be cause by too many sessions be stored on a server? Or anyone have any other ideas? First happened after uploading a few images through admin panel in open cart.
I am hosting a bunch of sites off of one server. SO it seems likely but has anyone run into this before?
Looks very likely that you've run out of space on the disk and so causing many things to fail. Try freeing up some space and try again.
I have looked around on the issue - but it seems that all I can find about it is people who are having the problem connecting to a local database or something (not really sure). I am having the problem on my website (any time I make an ajax call to a file that has a session_start())
Anyways, this is the error message I am getting:
Warning: session_start() [function.session-start]: open(/usr/local/apache/bin/httpd/sess_5840483107c1db9753c32214723b64a6, O_RDWR) failed: Not a directory (20) in /data/in/r/reiconsultants/www/employee/user_page_login.php on line 3

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/usr/local/apache/bin/httpd) in Unknown on line 0
I haven't touched the code in a while - and I can be quite sure that no one else has either, so I am not sure why the error is occurring. I read a bunch about people going in and setting the php.ini file, but I have never had to do that before - and can't even find the file.
Like I said - the error is occurring on my company website, not when trying to connect to a local database.
The error just popped up today - I got flooded with emails about it, and it is on more than one web page being hosted on the server - all the pages I have that include a session_start() at the top have the issue.
Could it be a server side issue that I can't fix? or what...
sorry if I am not descriptive enough - I have absolutely no idea what is going on, and therefore don't know what to say. Just ask me for any clarification you need.
Thanks!

The error is indicating that /usr/local/apache/bin/httpd/ is set as your folder to save session data in. Does that folder exist and is writable by the user Apache is running as? Does the Linux server have any other security measures like SELinux running that might be stopping writing to that directory?
Did you verify that the current setting of session.save_path is correct? Is /usr/local/apache/bin/httpd correct folder for saving session data?
Try set session.save_path = "/tmp" in you php.ini to ensure that problem is in folder.
you can also change the session path at run time:
string session_save_path([string $path])
