Hi,
I’m trying to move our environment from 2.6 to 3.0 so have setup one subnet to
be served by the new version. This appears to work w.r.t. issuing leases for
the subnet in question. However, it also crashes (seemingly randomly) with
kea-dhcp4: /usr/include/boost/smart_ptr/shared_ptr.hpp:728: typename
boost::detail::sp_member_access<T>::type boost::shared_ptr<T>::operator->()
const [with T = const isc::dhcp::Subnet4; typename
boost::detail::sp_member_access<T>::type = const isc::dhcp::Subnet4*]:
Assertion `px != 0' failed.
The environment is
Debian 12.11
Using Cloudsmith images:
# dpkg -l | grep kea
ii isc-kea-common 3.0.0-isc20250717111736 amd64 Common libraries
for the ISC Kea DHCP server
ii isc-kea-dhcp-ddns 3.0.0-isc20250717111736 amd64 ISC Kea DHCP
Dynamic DNS service
ii isc-kea-dhcp4 3.0.0-isc20250717111736 amd64 ISC Kea IPv4 DHCP
server
ii isc-kea-hooks 3.0.0-isc20250717111736 amd64 Hook libraries for
ISC Kea DHCP server
Is this a known issue and if not, what additional information is required to
debug it.
