As the core service update doesn't depend anymore on each other but only
on the inventory update, 2 can be launched almost at the same time.
As they can't run in parallel, the second one will only start when the
first one is done, meaning that it can take more than 180 seconds to
complete.

Increasing the timeout to 500 seconds should avoid the task to be
reported as failed when it just took longer to run.
