Although LOG.NSF comes out of the box with an automatic cleanup after "n" days, when you create domlog.nsf from domlog.ntf the agent to do that is disabled by default. Without paying attention, this file can quickly grow very very large. The default should be 10 days.
Set "Run web agents and web services concurrently?" to Enabled as default.
I see no reason for why this setting should be disabled in this day and time.
Of course you can always just switch it to enabled, but sometimes we forget.
