MYSQL/HTTPD resource issues in 5020
-
Sorry, I haven’t gotten back lately…had a sick child.
I have tried 5040 and 5042 this morning and I am still seeing almost complete CPU usage to the point that the web gui will talk 20-30 seconds to respond or not respond at all or not render most of the page.
I will try to go back to older ones to see where the problem was introduced.
-
Actually I’d recommend doing a full server reboot. I think what you’re seeing now is it catching up from all the bad stuff before. Of course it may be the case that something else is weird. Can you watch your Apache error log? Often when I see delays of loading as such there is usually something at a fast and large pace writing to the log files.
-
Rebooted…1 hour later still seeing same thing. I’m thinking there is something going on with apache. While i write this there is 259 httpd processes chewing up everything.
In the apache log, i get:
[Thu Oct 22 16:54:22 2015] [error] server reached MaxClients setting, consider raising the MaxClients setting
I just don’t know what would be causing this all of a sudden… Was something changed in the apache v/host settings in the past few weeks with the installer?

And i forgot.
The message only happens every once and a while in the error_log file.
-
@Adam-Taylor No, nothing has been changed on the vhost generation. Maybe you have a lot more computers running and creating new connections?
-
@Adam-Taylor Do you have a lot of clients? Are you using FOG_HOST_LOOKUP? (On hosts do you see the green/red dots when on list/search?)
-
@Adam-Taylor Please install the packet
lsofon your FOG server and runlsof -i :80to see who keeps all those apache processes busy. -
Right now i have 33525 mysql connections when i run “show status like ‘Con%’;” in mysql cli. And no…that was not a mistype
The connections are just not going away.Total registered hosts are 1892 of which about 1800 have the fog client.
Running lsof, I am a around 20-30 established connections at any one given time with about the same listening. All while the CPU is around 100%. Every once and a while it might spike to around 180 or so but then drop back down within 30 seconds or so.
FOG_HOST_LOOKUP was checked and I just unchecked it to see if that helps. So far I am not seeing a difference after a total system reboot.
I had to restart the mysqld process so that I could get to that setting as the web gui would not do anything. In that 2 minutes from a reboot, I am back upto 297 mysql connections.
BTW, I am running this on RedHat Enterprise 6.
Thanks!

What does
lsof -i :3306show? Is it all localhost connections?And what about
lsof -i :80? All connections from different clients?? -
Hmm, i’m getting this now too! FOG server is being crippled even after a reboot and wiping the hosts/reimporting (and Host lookup isn’t checked)
I am assuming that its because we have lots of PCs checking in but I didn’t think that so many processes would get generated!
Also lsof for port 80:

I added the following to the MySQL.class.php file to see how often it was creating a SQL connection:
public function connect()
try
if (!$this->link)
file_put_contents(‘php://stderr’, print_r(DATABASE_HOST, TRUE))It seems to be getting called 7-10 times per second currently.
Every single connection is p:127.0.0.1 so every connection is persistant…and they are not getting closed would be my guess.
Thanks!
Adam
-
3306 is all localhost connections.
80 is all different clients from around the campus.
-
I changed the DB connect from persistant to non persistant to test and see if the connections would then go away.
The connections go up much faster then before (what i expected since no reuse) but once again…they never go down.
That’s all i know to look at/try at the moment. Do appreciate your help in this!
Thanks!
Adam

@Adam-Taylor I know I keep asking the same things, but please reupdate and try again?
The only other thing that I think could be causing the issue is in line and hopefully this is corrected for. I have no real clue whether or not it is the case though.
-
The system is still getting hammered and all four cores are at 100% after a complete reboot.
Adam
-
Also, that 100% is always ~30% for mysql and the rest is chewed up with httpd processes.
Adam
-
@Adam-Taylor Tom has made some changes, update again.
-
Changes don’t seem to have fixed anything for me. Still see 100% usage after restart and update to 5078- basically the same as my screenshot earlier.
I do see this in the apache error log though, for all the clients that are trying to connect. Not sure itd make any difference though.
:[Mon Oct 26 14:55:09.526015 2015] [:error] [pid 3099] [client 10.240.5.151:57133] PHP Warning: mysqli::mysqli(): (HY000/2002): No such file or directory in /var/www/html/fog/lib/db/MySQL.class.php on line 18 -
@Trevelyan this makes absolutely no sense. It sounds like, from the error you are reporting, your server doesn’t have the mysqlnd driver stack for php as it can’t even find the mysqli object.
-
I am still seeing 100% usage for me to after the last update with mysql using~30% and httpd using the rest with LOTS of processes.
