Hi!<br>

<br>

You can force syslog-ng to close the source connections in case of a reload.</div>

<div>Type: yes or no<br>

<div>Default: yes<br>

<span>Description: Specifies whether connections to sources should be closed when syslog-ng is forced to reload its configuration (upon the receipt of a SIGHUP signal).

<br>

Note that this applies to the server (source) side of the syslog-ng connections, client-side (destination) connections are always reopened after receiving a HUP signal unless the keep-alive option is enabled for the destination.</span><br>

</div>

<div dir="auto">I know syslog-ng is not http2 but is there any side-channel mechanism a central server can use to make a client go away?</div>

<div dir="auto"><br>

</div>

<div dir="auto">The use case I am thinking is doing a rolling restart of a pool of syslog-ng central server.</div>

<div dir="auto">I think this could also be useful to cycle connections periodically, i.e. to rebalance connections to a central server.</div>
