Can't start DNS Resolver (SG-2220, 2.4.4_3)

teampolizei144

I changed to log level 2.
There is nothing in the DNS Resolver log file from the time I pushed the button to enable it.

KOM

And nothing new in the System - General log either? Any packages installed?

teampolizei144

No packages installed.
After clicking the start button on DNS Resolver I have a single entry:

Aug 10 20:39:48 kernel pid 60703 (unbound), uid 59: exited on signal 10

KOM

Signal 10 is a bus error:

In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions.

On POSIX-compliant platforms, bus errors usually result in the SIGBUS signal being sent to the process that caused the error. SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it is normally caused by a bug in software.[citation needed] Bus errors may also be raised for certain other paging errors; see below.

I've never heard of this being reported before for unbound. If the unit is under support then I would contact Netgate and ask about it.

My Contract type is 'Community Support' so I guess not.

kiokoman

try to launch unbound from the terminal with -v flags
unbound -d -vvv

teampolizei144

That gives me the following:

SSH:

Do you have a hostname set for the box?

teampolizei144

@KOM If you medan under System-General Setup, Then yes there I havet pfSense set as hostname for the SG2220.

kiokoman

try to reinstall 2.4.4 or try with 2.5.0 that use unbound 1.9.2

teampolizei144

I reinstalled 2.4.4_3 today. It starts correctly now. Fingers crossed that it stays like this.
Thanks for your guidance in this thread.
