After upgrade to 2.5.0 unbound crashing randomly

[maars.loonga]

I discovered that the unbound process is crashing from time to time after I upgraded to 2.5.0 yesterday.

unbound-checkconf: no errors in /usr/local/etc/unbound/unbound.conf

Feb 20 19:02:36 nixtraut kernel: pid 9903 (unbound), jid 0, uid 59: exited on signal 11
Feb 20 19:02:37 nixtraut dhcpleases[2070]: Could not deliver signal HUP to process 9903: No such process.
Feb 20 19:04:32 nixtraut dhcpleases[42865]: Could not deliver signal HUP to process 9903: No such process.

Every log file entrie regarding the

(unbound), jid 0, uid 59: exited on signal 11

comes after the dhcpleases message. Maybe it has something to do with the DHCP Server ? I could not reproduce the crash. after starting the service again, its working some time (hours). I'm on ipv4

Any one else discovered this behavior ?

This solution seems to be working for me.

I have the same exact issue !! it happened after upgrading pfSense from 2.4.x to 2.5.0

[chrcoluk]

try unticking "dhcp registration".

@chrcoluk I tried what you suggested and it's being stable for the last 10 hours...
do you think it's a bug?

Thanks

@deadsoul If it is staying down potentially yes.

DHCP registration will reload unbound every time a dhcp device connects or lease expires, this includes things like phones and consoles so can be quite frequent, generally I recommend to people to disable that option, there is another one for static dhcp which you can keep enabled.
