New Instance throws PDOException

[simond]

Good day,

I have been facing a problem for some time now dealing with following error:

Espo.ERROR: Uncaught Exception PDOException: "SQLSTATE[HY000] [2002] No such file or directory" at /var/www/application/Espo/ORM/EntityManager.php line 158 {"exception":"[object] (PDOException(code: 2002): SQLSTATE[HY000] [2002] No such file or directory at /var/www/application/Espo/ORM/EntityManager.php:158)"} []

This happened to my development system, I was running in a local docker connected to my local (containerless) mysql. Everything was working fine until suddenly it was not anymore.
The error seems to negate randomly changes I implemented in my extensions, as well as all log output. My log level in /data/config.php is set to debug.
Entities I create using extensions are still set up and I can create and edit them. However, methods implemented in /myextension/files/application/Modules/mynamespace/Services/Account.php are not called anymore, even though they used to work fine.

Not even setting up a completely new espo, with a fresh database seems to tackle the problem. The system immediately throws the error three times.
I am using MySQL v5.7.10 and started using espo 5.6.2 but upgraded to 5.6.9 without success.

Has anybody faced a similar issue or has any idea about possible solutions?

Thanks in advance and best wishes
Simon

Hello,
check please whether your local MySQL still runs.

[simond]

It is running and when I use the espo I can see new entries for example for users or accounts.
Restarting didn't help either

[simond]

Actually I can edit the espo code in /application/Espo/ORM/EntityManager.php and write stuff to the log.
I see now that it is triggered every minute without throwing the error.
Is there anything of interest I could have logged, to get more information about the issue?

[simond]

So I just found out that stuff not working could actually be a result of a conflict between two extensions. I expected the different namespaces to avoid this conflict, because I also address different methods. Is there any documentation about how files are loaded in espo?

However, the log is still not outputting anything from my custom code, neither do I get log output when installing extensions (which I got before).
I really wonder, what could've broken. I wasn't using the system when it first occurred.

I have been facing a same problem.

Pls, Give me the solution. If any...

simond, have you solve your issue. Its seems that you have some custom code error. I am going to moving this topic into the 'Developer help' branch of the forum. Hope someone will help you to solve it.

manu, please check whether you have set a proper DB user and password.
> Access denied for user 'root'@'localhost' (using password: NO)
you can check this and change in the EspoCRM/data/config.php file.
