Signals

On Unix systems, the NATS server responds to the following signals:
Signal
Result
SIGKILL
Kills the process immediately
SIGINT
Stops the server gracefully
SIGUSR1
Reopens the log file for log rotation
SIGHUP
Reloads server configuration file
SIGUSR2
Stops the server after evicting all clients (lame duck mode)
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
See the Windows Service section for information on signaling the NATS server on Windows.
