Signals

On Unix systems, the NATS server responds to the following signals:

The nats-server binary can be used to send these signals to running NATS servers using the -sl flag:

# Quit the server
nats-server --signal quit

# Stop the server
nats-server --signal stop

# Reopen log file for log rotation
nats-server --signal reopen

# Reload server configuration
nats-server --signal reload

# Lame duck mode server configuration
nats-server --signal ldm

If there are multiple nats-server processes running, or if pgrep isn't available, you must either specify a PID or the absolute path to a PID file:

nats-server --signal stop=<pid>
nats-server --signal stop=/path/to/pidfile
