Error message "Failed to read session data"

Post by Igor_77 » Sat Jan 12, 2019 5:52 pm

Hi guys!
I noticed my website is showing Error near 1 time in a week.

"sudo reboot" help's my machine to make it work, but I don't know the reason why that's happening.

When I use

Code: Select all

$error_reporting = 'maximum';
in configuration.php, it shows the message:

Code: Select all

Warning: session_start(): Failed to read session data: user (path: /var/lib/php/sessions) in /var/www/html/libraries/joomla/session/handler/native.php on line 260
Error: Failed to start application: Failed to start the session
Here is native.php string 260:

Code: Select all

...     // Ok to try and start the session
260                 if (!session_start())
...                {
...                        throw new RuntimeException('Failed to start the session');
...                }

I thought it can be a google indexing problem when a server is not able to give a response during high-speed indexing. Can this be a reason?

Can you also advice me how to configure my web server properly?
I use amazon EC-2 t2 micro (memory - 1.0 GiB, 1 vCPUs)

Thank you!

Here is the website info

Re: Error message "Failed to read session data"

When you say the error shows up once in a week, you mean other days you do not have this error?

Well, this post is different from what you said in the first post. You are talking about a migration from joomla 2.5 to 3.5, there are certainly many extensions that could not be used in joomla 3 unless you use the updated version and some do not have updated version at all. Even your template might not work in joomla 3.5(which is out dated too).
I tried migration from joomla 2.5 to 3.x once, I got to change many things that is why I decided to design my site from scratch.

Hi!
Kian, I don't understand why are you talking about some other posts. This is one post from me on this problem.

Yes, I don't have this problem everyday. But once in a week, or once in a week and a half I open my website and see white screen with an 1 word only - "Error"

Can someone help me?

You have session handler database. I have changed to session handler PHP because it's needed since 3.8.4 I think. It is very easy to change. For me I got problems with session handler database, because the Joomla session table grew to 25 GB, so I had to change because of that. So check the size of _sessions in your database. PHP session does not use the slower database so its faster also.

Session lifetime: 10080 (Default is 15) That is 7 days.

Ubuntu have a cron job that clears out old sessions. You may have collected a lot of sessions from visitors in the 7 days.
