need to expect outage when changing ip_conntrack_generic_timeout ?

an SAP application that has some kind of poor session handling is terminating after exactly 600 sec.

I now want to test changing this setting on the SG:

cc get packetfilter timeouts 'ip_conntrack_generic_timeout' => 600,

"conntrack_generic_timeout - INTEGER (seconds) default 600 Default for generic timeout. This refers to layer 4 unknown/unsupported protocols."

Do I need to expect something to restart automatically (or manually) after I have done that? Or do these settings apply on the fly?

Thanks in advance!
