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 <pid>' to kill it Is there an alternate solution?

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