  ## SIGNALS

- **SIGHUP**

  This signal causes a reconfiguration event, equivalent to running **traffic\_ctl config reload**.

- **SIGINT, SIGTERM**

  These signals cause **traffic\_manager** to exit after also shutting down **traffic\_server**.

- **SIGUSR2**

  This signal causes the **traffic\_manager** and **traffic\_server** processes to close and reopen their file descriptors for all of their log files. This allows the use of external tools to handle log rotation and retention. For instance, [logrotate(8)](/logrotate/8.md) can be configured to rotate the various Apache Traffic Server™ logs and, via the logrotate postrotate script, send a *-SIGUSR2* to the **traffic\_manager** process. After the signal is received, Apache Traffic Server™ will stop logging to the now-rolled files and will reopen log files with the originally configured log names.

## EXPONENTIAL BACK-OFF DELAY

If **traffic\_server** has issues communicating with  **traffic\_manager** after a crash, **traffic\_manager** will retry to start  **traffic\_server** using an exponential back-off delay, which will make **traffic\_manager** to retry starting **traffic\_server** from **1s** until it reaches the max ceiling time. The ceiling time is configurable  as well as the number of times that **traffic\_manager** will keep trying to start **traffic\_server**. *A random variance will be* *added to the sleep time on every retry*

**NOTE:**

For more information about this configuration please check *records.config*
