Intermittently the IPsec log receives every log line from charon twice, formatted slightly differently. The difference is that where there is a connection associated with the line, it appears in only one of the copies, while other lines are duplicated verbatim:

My log levels are currently set mostly to Audit, with a few on Control. This happens at the default levels, too.

I think it is sometimes possible to get the daemon out of this state by reloading it (apply changes). As you can see above, it did not work this time.
