-The most common cause for getting multiple copies of a server is using the socket manage RESTART button, which is flaky at best. Don't do this. If you need to restart a server you should do it manually. 1. Make sure you are logged into the right machine: ssh ctrscrut 2. If you are not sure see if the socket manager will tell you. If it doesn't have a look in the file: /ctrscrut/chara/etc/sock_manager/socket_manager.list 3. See if there are any ghosts running ps aux | grep esp_server Yes, it's hard to know which one it is with the esp servers. You can work out which ones are ghosts by typing the command tsockman |grep ctrscrut which will give you a list of the servers running on the machine you are interested in. Checking for non-matching PIDs will tell you which processes you need to stop. 4. Stop those processes: kill -9 PID1 PID2 …. 5.
