└─>Default timeout for requests (ms)
In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
Configures the default timeout after which any user submissions will
be forcefully terminated.

Beware setting this value lower, or close to heartbeat interval
rounded to whole seconds times three, in order to avoid allowing
misbehaving applications causing total rendering failure in unrelated
clients.

May be 0 to disable the timeout.
