After update of Fog Trunk - PHP Errors

Wayne Workman · Apr 26, 2016, 11:52 PM

@RipAU Try to bump it to two cores. See what happens.

RipAU · Apr 26, 2016, 11:55 PM

Okay I’m confused.

So you are saying even though the ESXi host is 64bit CPU and I installed the Fedora x86_64 version of the OS
and the kernel is listed as x86_64 GNU/Linux.
Because I only allocated 1 virtual CPU It installed as 32bit?

Wayne Workman · Apr 26, 2016, 5:59 PM

@RipAU x86_64 compiled code can run on 32 bit or 64 bit systems. Because you have one single core assigned, you have one processor. One single 32 bit core. Meaning that one single core is running 64 bit os because of how that os is compiled, and the instruction set that allows a 32 bit core to run 64 bit code. It’s slower, but works. If you intend to take real advantage of a 64 bit OS, you need two cores.

Plus, besides all that, if your load is high, wouldn’t it make sense to have more cores? And why are you being stingy with cores? I have an old core 2 duo in my basement I use as a VM host - it runs 4 VMs, each with 2 cores assigned. It does fine for my purposes. But point being, cores can be shared.

@Wayne-Workman

I’m happy to try a re-install and try to migrate the current database and images to an updated OS as I was going update to CentOS7 in future as I would like to be able to keep everything up to date.

I guess I generally will only give it a single CPU unless required as that was what I was told by a VMware engineer at a training session a few years ago and I can’t say I’ve even heard that only allocating a single 64bit capable CPU ends up running as a 32bit CPU on VMware ESXi.

Wayne Workman · Apr 27, 2016, 12:07 AM

@RipAU Pretty sure you can’t install CentOS 7 on a machine with one CPU. I’ve tried on an old Pentium 4 - didn’t work. I also tried once at work when I accidentally forgot to bump the cores from 1 to 4 for a VM - and CentOS 7 threw a nasty error when I tried to boot.

RipAU · Apr 27, 2016, 12:23 AM

@Wayne-Workman

No worries, I’ll look at spinning up an updated CentOS 7 machine to test the SVN with.

That said, I currently have a working version of CentOS 7 64bit with 1 Virtual CPU on the same ESXi and that didn’t have any problems being installed and everything is listed as 64bit by vmware etc.

I’ll give this a go over the next few days and report back.

Cheers,

Wayne Workman · Apr 27, 2016, 12:23 AM

@RipAU Well that is very interesting.

RipAU · Apr 26, 2016, 7:53 PM

Just tested again with a full update from the working version.

I’m still convinced it is an issue with the update in FOG with my server as the server load is so much lower before the update.

Just FYI there is about 120 lines of this that is the same.

I’ve also upped the CPU and the Memory just to test but it is the same result, which is why I’m thinking its more an issue with the FOG update than 32bit vs 64bit.

As well as errors in the HTTPD log listing PHP warnings.

Thanks everyone so far for the help

Edit: forgot the CPU from htop

Awesome, thanks.

Also just FYI after doing a fresh install of CentOS 7 that has been updated with the latest SVN version of Fog Version: 7332
I’m also getting the same errors from httpd

Hopefully its ok I am loading this thread up with screenshots of issues?

Ok, with some unscientific testing on the new server, I’m also getting higher CPU with only 2 hosts that have been registered.
Before I registered the hosts the CPU was near 0% now it is quite a bit higher.

I am suspecting the Fog Clients are basically flooding the FOG server as it seems to do a request every few seconds.
The Fog client logs are also filling up pretty quickly.

I’m basically getting the following over and over and over again until the fog.log starts again.

Hey guys.

Just FYI I updated to the latest trunk version and so far the CPU load has dropped quite substantially.
Between 2% and 20% depending on the traffic from the Clients.

The only remaining errors I have is a PHP Warnings

[Thu Apr 28 11:29:42.884801 2016] [:error] [pid 1551] [client 127.0.0.1:53970] PHP Warning:  session_destroy(): Trying to destroy uninitialized session in /var/www/html/fog/lib/fog/user.class.php on line 113

Aside from this everything else seems to be working correctly including the client not looping and stuck on authentication.

Fog Version: 7380

Thanks again guys.
I’m guessing this could be marked as solved as of Fog Version: 7380 for me.

Cheers.
