@tesparza Fixed by increase the number of connections.

mysql
SET GLOBAL max_connections = 200;
flush hosts;

login as root into the database.

@george1421 Thanks, snponyl.efi worked. It also worked with all the other models of PCs we have, thaknk you.

Having an issue with a specific Storage Node, I fresh installed CentOS and I fresh installed FOG on it. The Storage node shows up in the Storage Tab but it does not sync anything from the Master Node. DB passwords are correct so thats good. I dont have an ideas what Im missing. Ive fresh installed twice on two different machine and cannot get it to sync. Only happening at this specific campus.

Im getting errors with some devices not joining FOG

The authentication part Response Invalid security token.

How do I implement the link above.

@george1421

Running smooth so far. Yes it had 4GB before.

@george1421 Okay I have upgraded the RAM to 16gb. Will see how it goes. Thank you.

@george1421 Okay it seems to be running smoother, I will add more RAM, eventually I will transfer to a server.

@george1421 Okay interval changed to 300

@george1421

2000 + clients

Interval checkin time it 60 seconds

@george1421 Okay now everything is InnoDB, Server is running bad, web gui taking long time to load, can’t image. CPU usage is around 40%

FYI this is running of a Optiplex 7010 i5 quad core, 8gb ram

Do I maybe need to switch to a server?
