The pproxy parent understands the following signals:
SIGHUP | Reopen log file |
SIGTERM | The parent process will kill all its children and then shutdown itself cleanly. This is the same as sending the shutdown all command to the server. |
SIGQUIT | The parent process will shutdown cleanly, but the children are left running. This is the same as sending the shutdown parent command to the server. |
SIGINT | The parent will kill all its children and keep running itself. This is the same as sending the shutdown children command to the server. |
SIGPWR | The parent will close its listening sockets (i.e. stop accepting new connections) and then wait for all children to exit before shutting itself down cleanly. This is the same as sending the shutdown delayed command to the server. |
The child processes have no special signal handling, i.e. they will
die on receiving SIGTERM,
SIGQUIT, SIGINT, or
SIGHUP.
