I’m facing issues with some kernel panic but I don’t have any idea how to find which soft is exacly causing this issue. I’m trying to compile some soft on remote host using distcc software but my machines which are compiling are going down because of this issue.
Could you point me where shoud I start looking? What could cause this issue? Which tools should I use?
Here is kernel panic output:

It is quite difficult to tell what went wrong with this just piece of log you have pasted.
It seems like oops lead into kernel panic!.
Well,with helping you to find the real cause,I can help you with material to look into for further dissection of panic/crash.

link 2 : oops
Hope it helps you! 🙂
