linux - SSH hang at the end of one command

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:
