Not sure when this started, but I'm getting high CPU usage, about 50% from Little Snitch Daemon plus another 25% or so from the kernel task, which lasts about a minute or two after startup. It seems to be reading something from the disk, as the "bytes read" in Activity monitor rises steadily to about 1.4 GB, until it stops.
If I start up and log in as a different user, it doesn't happen. Strangely, as that user I don't even see Little Snitch Daemon listed in Activity monitor, though Little Snitch Configuration says filtering is on. When I log out and log in again as my regular account, then it happens.
How can I fix this?
macOS Sierra 10.12.6, LS 4.1.3
