Hi to everyone, thanks in advance.

I have a problem with My courses menu, with administrator user the menu work fine but with student user the moodle load is very large and show the next errors.

I try to disable all the plugins and uninstall language packs. Also the memory_limit in php.ini are in 8192M, next the versions of moodle, php, apache, mysql and OS  

Moodle 4.2+ (Build: 20230519)
OS:Amazon linux 2
Kernel: Linux 4.14.314-237.533.amzn2.x86_74
Architecture x86-64
webServer:Apache/2.4.57
PHP Version 8.1.16
MySql version 8.1.16

I review the requirements for moodle and I see that 4.2 are no compatible yet with PHP 8.1 and mysql 8.1 (can this be the problem?)

If I try to refresh in my course menu, sometime I get the next error

Error

Timed out while waiting for session lock.

Wait for your current requests to finish and try again later.

Hi Jonathan Herrera, You can go to your Moodle data folder just delete the session, temp, and local cache folders from there. After that purge the cache from the site administrator. See the result from Moodle users.
This process helps me earlier.
 
Thanks and regards,

Where? https://moodledev.io/general/releases/4.2 says PHP 8.1.x supported. MySQL 8.0 to Latest. It could be the "max_input_vars must be >= 5000" thing mentioned there.

Thanks, yeah I review and the requirements not are the problem. Aboout max inputs vars is in 5000 and show the same error.

Maybe about error log is a possible plugin the cause of the problem?

thanks

Same here, apparently setting the notification time lower than the session timeout works fine and removes the warning away.

I am facing the same issue and I want to try your fix, what do you mean by the "notification time" so far I found the session timeout which is the default 8 hours, but I did not find the "notification time".
can you please give us more details? THANKS
