Process of Port 8443 can't be killed

I tried to run JBOSS(v5.x)[ubuntu 18.04] and it was saying:

Deployment "WebServer" is in error due to the following reason(s): LifecycleException: Protocol handler initialization failed: java.net.BindException: Address already in use /0.0.0.0:8443
Deployment "jboss.web:service=WebServer" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.web:service=WebServer' **

So, tried to kill that process. To find the PID, used command lsof -i:8443 and found no process. Then tried sudo lsof -i:8443 and got this:

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
lxd     11526 root   22u  IPv4 696227      0t0  TCP localhost:8443 (LISTEN)
lxd     11526 root   25u  IPv4 699223      0t0  TCP localhost:41776->localhost:8443 (ESTABLISHED)
lxd     11526 root   26u  IPv4 701114      0t0  TCP localhost:8443->localhost:41776 (ESTABLISHED)

Then ran sudo kill -9 11526 //as without sudo, it was saying operation not permitted.

But again, when I run sudo lsof -i:8443 I can see new PID(each time I kill it, it runs in another PID!)
I am not sure what is wrong here and what to do.

`lxd` is a container service - try running `lxc list` to see if you have any containers running that occupy the port.

Try `lxd shutdown` and see if the ports still are occupied.

The ports have been occupied by the lxd container service.

To see your running containers:

lxc list

If nothing is running, the lxd daemon can be closed with:

lxd shutdown

This should free up the ports.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
