From e62702e3be51c64a68d48b455a23899c0bed6fae Mon Sep 17 00:00:00 2001 From: Jesse Pretorius Date: Wed, 26 Apr 2017 11:46:10 +0100 Subject: [PATCH] Reduce init restart/kill times The systemd unit 'TimeoutSec' value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. The 'RestartSec' value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using the *_init_config_overrides variables which use the config_template task to change template defaults.
