Not able to run 'gzserver' from ubuntu terminal

Hi, I am not able to run the command 'gzserver'. Whenever I run 'gzserver --verbose' i get the following display: [Err] [Master.cc:96] EXCEPTION: Unable to start server[bind: Address already in use]. There is probably another Gazebo process running. Please Help.

Are you sure you don't have another Gazebo process running? Have you tried killall gzserver?

Maybe another process is already using the port Gazebo is trying to use? Maybe try a different GAZEBO_MASTER_URI? For example:

export GAZEBO_MASTER_URI=http://localhost:11348

I tried changing the GAZEBO_MASTER_URI, it works fine only once.(I stopped the gzserver using 'ctrl+C' and then typing 'killall server'). Again if I try to run gzserver it shows the exact same error as before.

Maybe do killall gzserver? (note the gz)

Sorry..that was a typo. I meant 'killall gzserver'. I found a solution. It is to manually kill the process using the kill command giving the process's PID as a parameter before restarting gzserver. The commands I used is:

'ps aux' to find the process's PID and 'kill -9 ' to kill it

Is there an alternate solution?

Sorry, I have no clue as to why the killall command is not working.
