SSH hang at the end of one command

Question

Below command is not coming out :

ssh -x -l root  asr-bng-ubuntu "/usr/local/sbin/radiusd"

But process is getting started when i checked in console. Able to execute same command(/usr/local/sbin/radiusd) in console with no issues Also other commands are getting executed through ssh ( like ssh -x -l root asr-bng-ubuntu "ls")

The debug output from -vvv is this:

root@asr-bng-ubuntu's password: 
debug3: packet_send2: adding 64 (len 55 padlen 9 extra_pad 64)
debug2: we sent a password packet, wait for reply

Your command works correctly, ssh is waiting for the termination of the command to close the connection.

Look at this question on serverfault. And try the following:

ssh -x -l root server "/usr/local/sbin/radiusd &"
