Process Signaling

On Unix systems, the NATS Streaming Server responds to the following signals:

Signal

Result

SIGKILL

Kills the process immediately

SIGINT, SIGTERM

Stops the server gracefully

SIGUSR1

Reopens the log file for log rotation

The nats-streaming-server binary can be used to send these signals to run NATS Streaming Servers using the -sl flag:

# Reopen log file for log rotation
nats-streaming-server -sl reopen
‚Äč
# Stop the server
nats-streaming-server -sl quit

If there are multiple nats-streaming-server processes running, specify a PID:

nats-streaming-server -sl quit=<pid>

See the Windows Service section for information on signaling the NATS Streaming Server on Windows.
