[Freeswitch-users] How to reconnect to FS ?

How do I (re)connect to a running FS? (like -rv parameter in * ) to get the FS CLI prompt back? root@ubuntu:/usr/local/freeswitch/bin# ./freeswitch Cannot lock pid file /usr/local/freeswitch/log/freeswitch.pid. I get this message because FS is already running. Even better: where do I find the documentation for this problem. Rgds Henk
