I'm having a problem with my kea-dhcp4 server(s) falling over regularly with a segmentation fault, the line I'm seeing in the logs is this:
kernel: kea-dhcp4: segfault at 451 ip 00007fd8ee50c59c sp 00007ffeb5dada70 error 4 in libmysqlclient.so.18.0.0[7fd8ee4e4000+320000]
systemd: kea-dhcp4.service: main process exited, code=killed, status=11/SEGV
systemd: Unit kea-dhcp4.service entered failed state.
systemd: kea-dhcp4.service failed.
This is the current kea-1.2 built on a CentOS7 (fully updated) server and I also use an updated kernel: 4.11.2-1.el7.elrepo.x86_64 - although I did have this problem on the previous 1.1 release from the EPEL repo. The db is a MariaDB 10.2.6-1
and setup as a Galera cluster. As I mentioned in another recent post, I use Proxysql for access to the cluster but kea doesn't like that configuration so I connect kea directly to one of the db servers.
Has anyone else seen this? If there's any further debug logging you need just let me know.
