This script has been running fine for at least 3 years, and today it fails for the above error. From the webpage:
Warning: session_start() [function.session-start]: open(/tmp/sess_009d3afca81be6247b5879f26efdb132, O_RDWR) failed: No space left on device (28) in [file path to php script] on line 2.

I haven't come even close to the available filespace.

Hello fatrabbit!

Sorry for the trouble with the error on your site There was a temporary <a href="" target="_blank">disk space</a> issue our systems support was working on at that time. As soon as a server hits a critical disk space spike our systems support is immediately notified through our 24 our monitoring system and we fix it ASAP. Sorry for this. It's not something you would have seen in the <a href="" target="_blank">cPanel account stats</a>. You should see it working normally now. Sorry for the trouble

Best regards,
James R

I am also facing the same problem today (22rd July, 2013). The following is the error message I see when trying to access my site,
Session_Exception [ 1 ]: Error reading session data. ~ APPPATH/ko322/classes/kohana/session.php [ 325 ]
Fatal error: Uncaught exception 'ErrorException' with message 'Unknown: open(/tmp/sess_431fe3d2be468423af95694264b3c337, O_RDWR) failed: No space left on device (28)' in Unknown:0 Stack trace: #0 [internal function]: Kohana_Core::error_handler(2, 'Unknown: open(/...', 'Unknown', 0, NULL) #1 {main} thrown in Unknown on line 0
Mine is an open-classifieds version 2.0.4 version based site, hosted in Power Hosting pack.
Please help
Thank you

Hello Sibyperiyar,

Sorry to hear about the error that you're receiving. Typically, this message indicates that server hard drive might have been full. Our systems team monitors the server, and the last I checked it should be okay at this time.

Check out our article on monitoring disk space and cpu usage.

If you have any further questions or require further assistance, please let us know.
