As discussed on systemd-devel [1], in Fedora we get lots of abrt reports about the watchdog firing [2], but 100% of them seem to be caused by resource starvation in the machine, and never actual deadlocks in the services being monitored. Killing the services not only does not improve anything, but it makes the resource starvation worse, because the service needs cycles to restart, and coredump processing is also fairly expensive. This adds a configuration option to allow the value to be changed. If the setting is not set, there is no change. My plan is to set it to some ridiculusly high value, maybe 1h, to catch cases where a service is actually hanging.
