Fatal error when logging out on Mercury AMI

Posted by paradox281 on December 22, 2009 at 12:48am

I am using the latest 32bit Mercury AMI, and I get this error message most of the times I log out. Please help.

Fatal error: session_start() [function.session-start]: Failed to initialize storage module: user (path: /var/lib/php5) in /var/www/pressflow/includes/bootstrap.inc on line 1550

Reproducing

In order to reproduce this, what is the instance size you use?

I'm using the small instance

I'm using the small instance size.

If I log in and log right out, it seems normal. but if I stayed logged in for awhile, and try logging out I get the error. Let me try to find out if I can reproduce this error consistently. Btw, www.airsoftpx.com is my website if you want to try it there.

I've seen this come up in a few different contexts, but have not been able to reliably reproduce it either. Would love to get a grip on the issue though, as it's quite annoying.

These two bug reports might be of interest. (Disclaimer: I'm yet to use Mercury :) ). What version of PHP is the AMI using?

I am using almost the same setup 32bit Mercury small instance, however I replaced pressflow with a standard Aegir and use pressflow for the platforms. I have not noticed this error message yet and my instance has been up 467 Hrs with tons of log in/out.

I wonder why ive not seen it yet.. im not using aggressive/external cache just yet though, ill give that a test when I get a spare moment. Perhaps some of the system tweaks performed when I installed Aegir may have prevented the issue too .. I dunno.

Has everyone else seen this issue sporadically? That bug report Mig posted above seems to fit really well, at least the symptoms do.

Does this help?

I think I can reproduce the problem consistently. I can log out just fine, when I am on a non secure section on the website (http), but when I am on a secure section of the website (https) and try to log out I get this error.
