Extremely slow loading combined with 'SessionHandler::read(): Unable to clear session lock record'

[Brecht]

Hello,

 

 

I've searched but not found posts that relate to my current problem.

 

Here's the situation:

 

I have installed a new 1.7.2 version prestashop on my domain.

It has the Dutch language package.

 

Php version is 7.1

CGI is currently disabled.

I have a 'Let's Encrypt' SSL certificate that is valid at this moment.

The SSL is also activated for the complete site.

 

 

Server info:

Serverinformatie: Linux #1 SMP Wed Oct 26 10:25:49 UTC 2016 x86_64

Server softwareversie: LiteSpeed

PHP-versie: 7.1.4

Geheugenlimiet: 256M

Maximale uitvoeringstijd: 90

Maximale bestandsgrootte voor uploads: 40M

 

Database info:

MySQL versie: 5.6.21-70.1-log

MySQL-server: mysql.linuxsystems.be

MySQL-naam: sf_db

MySQL-gebruiker: sf_user

Tabellen voorvoegsel: ps_

MySQL-engine: InnoDB

MySQL-driver: DbPDO

 

All caching is disabled as well as all external modules (I activated the setting and also didn't install anything yet).

 

The problem I'm having is that (if a page loads) it takes ages.

After enabling debugging I see the following error returning:

 

Warning op lijn 417 in bestand /web/simplifine/modern-knight.be/www/app/cache/dev/classes.php
[2] SessionHandler::read(): Unable to clear session lock record

 

 

Could anybody offer me some insight as to what I might be doing incorrectly ?

 

 

Thanks in advance for your answers.

Try to disable memcached if you have it running. Or try setting this in memcached.ini.

memcached.sess_lock_wait_min = 250;

Unfortunately it's already disabled. No change .

Do you have any other suggestions ?

 

Update: 

It loads in incognito mode but the front-end only.

As soon as there is any session tracking the thing hangs.

Unfortunately I don't have anything else to offer.

Hello,

 

Just to inform you. This issue was due to erroneous settings on the Memcached system on the server.

High time delay with my original hosting to address the issue forced me to change hosting. 

No more issues at this point.

 

Gr.
