[Pedrope]

I'm not sure if this post is in the right section

Hi, I try to access my server today, but it was not possible at the first try. After several attempts It worked, and the php-error.log has a lot of this lines

#3 /home/keyhelp/www/keyhelp/cronjob/mastercronjob.php(75): DatabaseConnection->__construct()
#4 {main}

Hallo,

it seems that the MySQL Server was not running or at max connection limit.

[Pedrope]

Hi, thanks for your answer Florian, but the MySql server is OK.

It doesn't always happen

Thanks

Hallo,

check the logs of the mysql server and dmsg. Maybe the MySQL was killed by the OOM killer. Run mysqltuner to see if the settings of your MySQL server are OK.

But this is no Keyhelp related error.

[Pedrope]

Thanks Florian, I'll do it

One question... can I reinstall mariadb without causing problems on the server?
or is it better to reinstall the panel from scratch?

Thanks in advance

One question... can I reinstall mariadb without causing problems on the server?

Why do you want to reinstall?

That won't fix any misconfiguration.

First, check that you can connect to mysql with the credentials from /etc/keyhelp/config/config.json.

[Pedrope]

24unix, thanks for you response, Indeed I can connect without problems with the credentials.
The problem is that sometimes the Mysql goes down and I don't understand the reason.

I can't find the mysql server log (/var/log/mysql/ --> doesn't show anything), Where can I find this log file?

by the way, the dmesg command does not show anything related to mysql

I appreciate any help to solve this

Thanks

You can try:

Code: Select all

journalctl -u mariadb.service -f

[Pedrope]

ok, this is the output

Apparently here is the error

nov 04 01:00:43 nautilus systemd[1]: mariadb.service: A process of this unit has been killed by the OOM killer.

As Florian guessed OOM. (Out of memory)

What does

Code: Select all

free

output?

[Pedrope]

this is the output

Code: Select all

root@nautilus:/# free
               total        used        free      shared  buff/cache   available
Mem:          999824      518992      162076       84348      318756      256892
Swap:         262140      262088          52

it seems to be the memory, not having enough, kills the mysql processes to protect the server.
It is right?

Yes, that's the job of the OOM killer.

You could try to decrease memory usage (antivirus stuff running?) or increase swap space.
But best solution would be to upgrade RAM.

[Pedrope]

Thanks 24unix, it's clear what I have to do, it's my job now.
I really appreciate your help

Can someone mark this thread as resolved?

Best regards

Pedrope

In the log is a second error hidden which should be solved

Could not increase number of max_open_files to more than 32768 (request: 131204)
