Sorry for reverting back late on this. I was able to try the suggested solution. There was no .slice unit file on the system by default. So, I created the .slice file for my services.
# cat /usr/lib/systemd/system/hacl-cfg.slice [Unit] Description=hacl-cfg Slice DefaultDependencies=no After this I was able to verify that there is no Conflicts with shutdown.target. Still I am getting the same error. Oct 02 03:41:05 gamma1 systemd[1]: Preset files say disable hacl-cfg.socket. Oct 02 03:41:05 gamma1 systemd[1]: hacl-cfg.socket: Incoming traffic Oct 02 03:41:05 gamma1 systemd[1]: hacl-cfg@8-127.0.0.1:5302-127.0.0.1:45234.service: Trying to enqueue job hacl-cfg@8-127.0.0.1:5302-127.0.0.1:45234.service/start/replace Oct 02 03:41:05 gamma1 systemd[1]: hacl-cfg.socket: One connection closed, 1 left.

As I mentioned earlier this works fine for UDP service, for TCP service above error is seen. Below are UDP logs, where UDP socket is able to spawn a new service during shutdown.

Any insights would be very helpful.
