@jmoore It is when I restart the service. and then about 30-90 seconds later it stops again.

@DustinB3403 What do you mean by using top?

The top command. But it isn't a good tool for that. For immediately memory use this instead free -m

Total 3948 used 343

The full output would be best, but that gives us a starting point.

root@www:~# free -m
             total       used       free     shared    buffers     cached
Mem:          3948        347       3601          0          5         37
-/+ buffers/cache:        304       3644
Swap:          511         19        492

Yup, that is WAY more than enough memory

Had way more before we downsized. Went the lowest I could while making sure we had enough space for the site itself.

scottalanmiller

Okay, so at this point we need logs.

And, and those two sar reports.

From what location? /var/ or /etc/ ?

You need to enable sar collection. It's very important for all investigation.

Back from lunch. I see Scott is here and he is infinitely more qualified lol. I am betting it is the data base. Did you ever do a status on mysql to see if it was responding?

root@www:~# mysqladmin -u root -p status
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

Even if I run service mysql restart and then run the status I get the same issue.

Still cannot run the SAR or SAR -R requests. Even after an apache restart and a reboot of the server

@wls-itguy Did you try with sudo?

@wls-itguy Did you try with sudo?

I'm logged in as root

But I tried anyway and it didn't change anything

WLS-ITGuy

Would a re-install of MySQL help?

jmoore

Ok to me it just sounds like mysql is in a funk. It also appears it is still running. I think you should try to kill the process and then start it back up. Do this from terminal:

ps aux
then look for process ID of mysql
from terminal : kill -9 ID
then from terminal again: service start mysql
