In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.

### `shutdown` event { #shutdown-event }

To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:

	healStoppedStatus                      = "stopped"
	healFinishedStatus                     = "finished"
)

const (
	// a heal sequence with this many un-consumed heal result
	// items blocks until heal-status consumption resumes or is
	// aborted due to timeout.
	maxUnconsumedHealResultItems = 1000

	// if no heal-results are consumed (via the heal-status API)
	// for this timeout duration, the heal sequence is aborted.

                if (account.getLockoutExpiry().isAfter(Instant.now())) {
                    totalAttemptsBlocked.incrementAndGet();
                    throw new SmbException("Account '" + username + "' is locked out until " + account.getLockoutExpiry());

                    account.reset();
