Kernal panic - not syncing: Attempted to kill init!

@Tom-Elliott
So I checked the partition size’s:

[root@localhost fogadmin]# df -h --o

I re-seated the memory and now I’m getting this new screen:

Should I start a new post for this one?

[ManofValor]

@ManofValor
By the way, this screen is consistent now.

[Tom Elliott]

@ManofValor Then, based on the fact that it seems to be pointing at network, I’d say check your patch cable and make sure the connection is solid.

[ManofValor]

Not sure if this was the right thing to try but I ran:

git clone git://git.ipxe.org/ipxe.git

And it ended with this:

  [AR] bin/blib.a
ar: creating bin/blib.a
  [HOSTCC] util/zbin
util/zbin.c:7:18: fatal error: lzma.h: No such file or directory
 #include <lzma.h>
                  ^
compilation terminated.
make: *** [util/zbin] Error 1

[Tom Elliott]

@ManofValor No, it didn’t. That looks you downloaded the ipxe repository then ran:

make

AFter that, as it it was building, you received that information.

LZMA, I would suspect, would be you needing the lzma-devel packages (not sure where but I think it’s xzutils-devel and xzutils from fedora/redhat based.)

[Tom Elliott]

@Tom-Elliott Sorry for redhat/centos/fedora it appears:

yum -y install xz-devel
ldconfig

Should do the trick (no guarantees) though I don’t know why you need to download the ipxe repository.

[ManofValor]

@Tom-Elliott
I just tried it cause I went to https://ipxe.org/0f0a6039, from the screen shot, and that was one of the suggestions.
I’ll try that and see…

[ManofValor]

Well, that didn’t work. The cable is fine. I get internet and I can ping it.

[Tom Elliott]

@ManofValor Cable being fine doesn’t tell us much. (You pulled it and put in a new one just in case?)

Where are you getting the ipxe error from? The error from iPXE is not a kernel panic.

[Tom Elliott]

Seeing as the error that you’re seeing states “Connection reset” that could mean any number of things, though I wouldn’t know where to begin looking.

Maybe you have port security turned on? I don’t know. If that’s the problem, now, it would seem to indicate (probably) a problem with the specific system you’re running into these issues with.

First it was ram, now the nic won’t maintain connection, etc…???

[ManofValor]

I started thinking the same thing. I’m going to try a different PC and see what happens.

[ManofValor]

I believe httpd is the problem right now. I tried to go into FOG management and got an "Unable to connect"page. So I tried to run the installer and apache2 failed to start. I’ve looked at a lot of sites with this similar issue and cannot determine a solution for me. I’ve started, restarted, stopped, reloaded, kill, and tried to update apache/httpd. Here is some info that I hope can help.

I just don’t understand it enough to completely know what I’m looking at.

[Tom Elliott]

@ManofValor I’m going to guess that your main filesystem (which doesn’t appear to be a problem) is full again. I say that because all was working, then it wasn’t.

[Tom Elliott]

@ManofValor that and httpd has absolutely nothing with DHCP, TFTP, or the fos system with kernel panics.

[ManofValor]

File system still seems fine:

OK, I fixed the Apache/HTTPD issue. After much, much, much searching I found this site for a fix and it worked for me.
http://awsadminz.com/httpd-service-main-process-exited-kill-cannot-find-process/
Should I post a separate tutorial as a fix for this issue?
As for the kernel thing, I tried a different PC and it is working fine. I guess I’ll have to figure that one out.
