dhcpd crashes

Chip Pleasants
Hi all,

I'm hoping someone could point me in the right direction with an issue I'm seeing with dhcpd 4.2.2 on Raspbian.  Multiple times per day dhcpd just stops.  I do not see anything in the logs.  I was able to do a trace file listed below.  I would upgrade to a new version, but it doesn't seem like Raspbian has an updated version. I can provide configs if required. I do have ddns, v4, and v6 running. Any help is suggested. 


Thanks,
Chip

Re: dhcpd crashes

This is likely one of the issues we fixed in the DDNS code - we had some issues
with stale pointers and such.  As we haven’t heard of any issues for a while I believe
they are fixed now.  

It would be best to upgrade - we released 4.2.8 almost a year ago and that is
going to be the last release in the 4.2.x series so 4.2.2 is fairly old.
