I get some metrics:
Processes before crash:
Processes in the moment of crash:
Memory and CPU usage:
Total RAM 3.6G. Does someone have any ideas?

httpd is the largest memory user; decrease its settings, especially the number of 'children' it is willing to spawn. (Under 10 should suffice for most small installations.)
max_connections: 70 table_cache: 472 -- Cut each of those in half; this will help a little with memory allocation.
Next time the CPU hits 100%, do SHOW FULL PROCESSLIST; in MySQL. That may give you a clue of what runaway queries you have. Then we can focus on them. If that fails, turn on the slowlog; it will catch some of them.
Consider moving to an 8GB server. (Is this a cloud server?)

Mgt Development Environment - MySQL suddenly won't start

I have 4 containers using mgt-commerce/mgt-development-environment-7.2. Basically everything runs well until I cannot access the control panel. It returns 500.
After checking the services, logs, etc, it seems like mysql is unable to start. Here is the error log captured in /var/log/mysql/error.log during starting mysql service using sudo service mysql start.

Is there anyone using this image ever getting this kind of error?
Update
It seems like mysql doesn't have the access to a particular file(s) or directory(ies), but I'm not sure which file(s) or directory(ies) . Here is the permission of mysql data directory:
clp#magento2dev:/$ ls -la /var/lib | grep mysql

PS: /var/lib/mysql directory is owned by mysql (there is one more directory mysql~ which is empty)
drwxr-xr-x 8 mysql mysql 4096 May 23 11:05 mysql
drwxr-xr-x. 3 mysql mysql 26 Feb 4 2015 mysql~
Please provide some suggestion. How can I restart my mariadb, I have important database under mariadb.
From the last line of error
[ERROR] /usr/libexec/mysqld: unknown variable 'extra-lsndir=/var/tmp'
It is clear that this variable is not known so try to comment it from /etc/my.cnf and try again.
# Point the following paths to different dedicated disks
tmpdir = /var/tmp
extra-lsndir = /var/tmp ------> Comment this line
target-dir=/var/tmp
I hope it will help.

mysql runing well these days, but it can not start suddenly today

I have a server running wordpress on it.

So I checked server, found mysql service was shutdown.

Database connection error in wordpress

My site is on Wordpress and is hosted on a VPS server. The traffic is not much but the database connect error is displayed many times, and then I had to restart MySQL.
I've checked the MySQL error file log. Here is a certain portion of the log.

I do not understand anything about this. Could anyone explain the issue to me or suggest a fix?

MySQL Will Not Start - InnoDB: Database was not shut down normally! InnoDB: Starting crash recovery

I am having some problems with MySQL - the service has stopped and will not restart.
I have an XAMPP stack running MediaWiki which is what uses the MySQL database. The server itself is a VM running Windows 2003 SP2 with 512MB RAM.
Below is an extract from the mysql_error.log

Fixes Attempted:
Tried starting from services - error 1067 - "The Process Terminated unexpectedly"
Tried restarting the server itself - no good
Tried moving the ib_logfile0 and ib_logfile1 files from directory and restarting server no good
Tried killing the PID of MySQL from command prompt in case it was still running but it was not running.
If anybody could point me in the right direction it would be much appreciated.
NB> I am also trying to get the RAM of the server increased in case that is the issue. At the moment of the 512MB only about 90MB is free.
thanks
